Behaving safely under pressure: The effects of job demands, resources, and safety climate on employee physical and psychosocial safety behavior.

PubMed

Bronkhorst, Babette

2015-12-01

Previous research has shown that employees who experience high job demands are more inclined to show unsafe behaviors in the workplace. In this paper, we examine why some employees behave safely when faced with these demands while others do not. We add to the literature by incorporating both physical and psychosocial safety climate in the job demands and resources (JD-R) model and extending it to include physical and psychosocial variants of safety behavior. Using a sample of 6230 health care employees nested within 52 organizations, we examined the relationship between job demands and (a) resources, (b) safety climate, and (c) safety behavior. We conducted multilevel analyses to test our hypotheses. Job demands (i.e., work pressure), job resources (i.e., job autonomy, supervisor support, and co-worker support) and safety climate (both physical and psychosocial safety climate) are directly associated with, respectively, lower and higher physical and psychosocial safety behavior. We also found some evidence that safety climate buffers the negative impact of job demands (i.e., work-family conflict and job insecurity) on safety behavior and strengthens the positive impact of job resources (i.e., co-worker support) on safety behavior. Regardless of whether the focus is physical or psychological safety, our results show that strengthening the safety climate within an organization can increase employees' safety behavior. Practical implication: An organization's safety climate is an optimal target of intervention to prevent and ameliorate negative physical and psychological health and safety outcomes, especially in times of uncertainty and change.

Social safety, self-rated general health and physical activity: changes in area crime, area safety feelings and the role of social cohesion.

PubMed

The aim of this study was to examine whether changes over time in reported area crime and perceived area safety were related to self-rated general health and physical activity (PA), in order to provide support for a causal relationship between social safety and health. Additionally, we investigated whether social cohesion protects the residents against the negative impact of unsafe areas on health and PA. Multilevel logistic regression analyses were performed on Dutch survey data, including 47,926 respondents living in 2974 areas. An increase in area level unsafety feelings between 2009 and 2011 was associated with more people reporting poor general health in 2012 in that area, but was not related to PA. Changes in reported area crime were not related to either poor general health or PA. The social cohesion in the area did not modify the effect of changes in social safety on health and PA. The results suggest that tackling feelings of unsafety in an area might contribute to the better general health of the residents. Because changes in area social safety were not associated with PA, we found no leads that such health benefits were achieved through an increase in physical activity. Copyright © 2014 Elsevier Ltd.

Crime, perceived safety, and physical activity: A meta-analysis.

PubMed

Rees-Punia, Erika; Hathaway, Elizabeth D; Gay, Jennifer L

2018-06-01

Perceived safety from crime and objectively-measured crime rates may be associated with physical inactivity. The purpose of this meta-analysis is to estimate the odds of accumulating high levels of physical activity (PA) when the perception of safety from crime is high and when objectively-measured crime is high. Peer-reviewed studies were identified through PubMed, Web of Science, ProQuest Criminal Justice, and ScienceDirect from earliest record through 2016. Included studies measured total PA, leisure-time PA, or walking in addition to perceived safety from crime or objective measures of crime. Mean odds ratios were aggregated with random effects models, and meta-regression was used to examine effects of potential moderators: country, age, and crime/PA measure. Sixteen cross-sectional studies yielded sixteen effects for perceived safety from crime and four effects for objective crime. Those reporting feeling safe from crime had a 27% greater odds of achieving higher levels of physical activity (OR=1.27 [1.08, 1.49]), and those living in areas with higher objectively-measured crime had a 28% reduced odds of achieving higher levels of physical activity (OR=0.72 [0.61, 0.83]). Effects of perceived safety were highly heterogeneous (I 2 =94.09%), but explored moderators were not statistically significant, likely because of the small sample size. Despite the limited number of effects suitable for aggregation, the mean association between perceived safety and PA was significant. As it seems likely that perceived lack of safety from crime constrains PA behaviors, future research exploring moderators of this association may help guide public health recommendations and interventions.

Physical design correlates of efficiency and safety in emergency departments: a qualitative examination.

PubMed

Pati, Debajyoti; Harvey, Thomas E; Pati, Sipra

2014-01-01

The objective of this study was to explore and identify physical design correlates of safety and efficiency in emergency department (ED) operations. This study adopted an exploratory, multimeasure approach to (1) examine the interactions between ED operations and physical design at 4 sites and (2) identify domains of physical design decision-making that potentially influence efficiency and safety. Multidisciplinary gaming and semistructured interviews were conducted with stakeholders at each site. Study data suggest that 16 domains of physical design decisions influence safety, efficiency, or both. These include (1) entrance and patient waiting, (2) traffic management, (3) subwaiting or internal waiting areas, (4) triage, (5) examination/treatment area configuration, (6) examination/treatment area centralization versus decentralization, (7) examination/treatment room standardization, (8) adequate space, (9) nurse work space, (10) physician work space, (11) adjacencies and access, (12) equipment room, (13) psych room, (14) staff de-stressing room, (15) hallway width, and (16) results waiting area. Safety and efficiency from a physical environment perspective in ED design are mutually reinforcing concepts--enhancing efficiency bears positive implications for safety. Furthermore, safety and security emerged as correlated concepts, with security issues bearing implications for safety, thereby suggesting important associations between safety, security, and efficiency.

Safe To Walk? Neighborhood Safety and Physical Activity Among Public Housing Residents

PubMed Central

Bennett, Gary G; McNeill, Lorna H; Wolin, Kathleen Y; Duncan, Dustin T; Puleo, Elaine; Emmons, Karen M

2007-01-01

Background Despite its health benefits, physical inactivity is pervasive, particularly among those living in lower-income urban communities. In such settings, neighborhood safety may impact willingness to be regularly physically active. We examined the association of perceived neighborhood safety with pedometer-determined physical activity and physical activity self-efficacy. Methods and Findings Participants were 1,180 predominantly racial/ethnic minority adults recruited from 12 urban low-income housing complexes in metropolitan Boston. Participants completed a 5-d pedometer data-collection protocol and self-reported their perceptions of neighborhood safety and self-efficacy (i.e., confidence in the ability to be physically active). Gender-stratified bivariate and multivariable random effects models were estimated to account for within-site clustering. Most participants reported feeling safe during the day, while just over one-third (36%) felt safe at night. We found no association between daytime safety reports and physical activity among both men and women. There was also no association between night-time safety reports and physical activity among men (p = 0.23) but women who reported feeling unsafe (versus safe) at night showed significantly fewer steps per day (4,302 versus 5,178, p = 0.01). Perceiving one's neighborhood as unsafe during the day was associated with significantly lower odds of having high physical activity self-efficacy among both men (OR 0.40, p = 0.01) and women (OR 0.68, p = 0.02). Conclusions Residing in a neighborhood that is perceived to be unsafe at night is a barrier to regular physical activity among individuals, especially women, living in urban low-income housing. Feeling unsafe may also diminish confidence in the ability to be more physically active. Both of these factors may limit the effectiveness of physical activity promotion strategies delivered in similar settings. PMID:17958465

Physical Activity and Safety From Crime Among Adults: A Systematic Review.

2016-06-01

The aim of this study was to review the evidence to date on the association between physical activity and safety from crime. Articles with adult populations of 500+ participants investigating the association between physical activity and safety from crime were included. A methodological quality assessment was conducted using an adapted version of the Downs and Black checklist. The literature search identified 15,864 articles. After assessment of titles, abstracts and full-texts, 89 articles were included. Most articles (84.3%) were derived from high-income countries and only 3 prospective articles were identified. Articles presented high methodological quality. In 38 articles (42.7%), at least one statistically significant association in the expected direction was reported (ie, safety from crime was positively associated with physical activity). Nine articles (10.1%) found an association in the unexpected direction and 42 (47.2%) did not find statistically significant associations. The results did not change when we analyzed articles separately by sex, age, type of measurement, or domains of physical activity evaluated. The current evidence, mostly based on cross-sectional studies, suggests a lack of association between physical activity and safety from crime. Prospective studies and natural experiments are needed, particularly in areas with wide crime variability.

OBJECTIVE: To critically review evidence on the safety and efficacy of physical restraints for the elderly and to provide family physicians with guidelines for rational use of restraints. DATA SOURCES: Articles cited on MEDLINE (from 1989 to November 1994) and Cinahl (from 1982 to 1994) under the MeSH heading "physical restraints." STUDY SELECTION: Articles that specifically dealt with the safety and efficacy of restraints and current patterns of use, including prevalence, risk factors, and indications, were selected. Eight original research articles were identified and critically appraised. DATA EXTRACTION: Data extracted concerned the negative sequelae of restraints and the association between restraint use and fall and injury rates. General data about current patterns of restraint use were related to safety and efficacy findings. DATA SYNTHESIS: No randomized, controlled trials of physical restraint use were found in the literature. A variety of study design, including retrospective chart review, prospective cohort studies, and case reports, found little evidence that restraints prevent injury. Some evidence suggested that restraints might increase risk of falls and injury. Restraint-reduction programs have not been shown to increase fall or injury rates. Numerous case reports document injuries or deaths resulting from restraint use or misuse. CONCLUSIONS: Although current evidence does not support the belief that restraints prevent falls and injuries and questions their safety, further prospective and controlled studies are needed to clarify these issues. Information from review and research articles was synthesized in this paper to produce guidelines for the safe and rational use of restraints. PMID:8969858

2017-12-01

With more than 60 installed magnetic resonance imaging (MRI) systems worldwide operating at a magnetic field strength of 7T or higher, ultrahigh-field (UHF) MRI has been established as a platform for clinically oriented research in recent years. Profound technical and methodological developments have helped overcome the inherent physical challenges of UHF radiofrequency (RF) signal homogenization in the human body. The ongoing development of dedicated RF coil arrays was pivotal in realizing UHF body MRI, beyond mere brain imaging applications. Another precondition to clinical application of 7T MRI is the safety testing of implants and the establishment of safety concepts. Against this backdrop, 7T MRI and MR spectroscopy (MRS) recently have demonstrated capabilities and potentials for clinical diagnostics in a variety of studies. This article provides an overview of the immanent physical challenges of 7T UHF MRI and discusses recent technical solutions and safety concepts. Furthermore, recent clinically oriented studies are highlighted that span a broad application spectrum from 7T UHF brain to body MRI. 4 Technical Efficacy: Stage 1 J. Magn. Reson.

The role of neighborhood walkability and safety in mediating the association between education and physical activity has not been quantified. We used data from the 2010 and 2012 Communities Putting Prevention to Work Behavioral Risk Factor Surveillance System and structural equation modeling to estimate how much of the effect of education level on physical activity was mediated by perceived neighborhood walkability and safety. Neighborhood walkability accounts for 11.3% and neighborhood safety accounts for 6.8% of the effect. A modest proportion of the important association between education and physical activity is mediated by perceived neighborhood walkability and safety, suggesting that interventions focused on enhancing walkability and safety could reduce the disparity in physical activity associated with education level.

Background Mental health conditions are among the leading non-fatal diseases in middle-aged and older adults in Australia. Proximal and distal social environmental factors and physical environmental factors have been associated with mental health, but the underlying mechanisms explaining these associations remain unclear. The study objective was to examine the contribution of different types of physical activity in mediating the relationship of social and physical environmental factors with mental health-related quality of life in middle-aged and older adults. Methods Baseline data from the Wellbeing, Eating and Exercise for a Long Life (WELL) study were used. WELL is a prospective cohort study, conducted in Victoria, Australia. Baseline data collection took place in 2010. In total, 3,965 middle-aged and older adults (55–65 years, 47.4% males) completed the SF-36 Health Survey, the International Physical Activity Questionnaire, and a questionnaire on socio-demographic, social and physical environmental attributes. Mediation analyses were conducted using the MacKinnon product-of-coefficients test. Results Personal safety, the neighbourhood physical activity environment, social support for physical activity from family or friends, and neighbourhood social cohesion were positively associated with mental health-related quality of life. Active transportation and leisure-time physical activity mediated 32.9% of the association between social support for physical activity from family or friends and mental health-related quality of life. These physical activity behaviours also mediated 11.0%, 3.4% and 2.3% respectively, of the relationship between the neighbourhood physical activity environment, personal safety and neighbourhood social cohesion and mental health-related quality of life.

Parental safety concerns--a barrier to sport and physical activity in children?

PubMed

Boufous, Soufiane; Finch, Caroline; Bauman, Adrian

2004-10-01

To examine the extent to which parents and carers perceive injury and safety risks as serious enough to prevent or discourage their children, aged 5-12 years, from participating in sports/physical activity and to identify factors that influence these perceptions. An analysis of the 2001 New South Wales Child Health Survey. More than one-quarter of parents/ carers of active children aged 5-12 years reported discouraging or preventing children from playing a particular sport (34.7% for boys and 16.6% for girls) because of injury and safety concerns. In boys, the most frequently discouraged sport was rugby league (23.2%), followed by rugby union (7.5%) and Australian rules football (2.8%). Among girls, the most frequently discouraged activities were rollerblading (2.7%), rugby league (2.3%) and soccer (2.1%). Multivariate analysis shows that factors independently associated with parents' decision to prevent/discourage their child from engaging in sport/physical activity include their child's age and gender, language spoken at home, presence of disability, and the respondent's relation to the child. Efforts need to be made to modify some sports/ activities, such as football codes, in order to minimise injury and to ensure that children continue enjoying their favourite activity well into adulthood. Guidelines designed to promote physical activity among children and young adolescents need to take into account parental concerns regarding the associated risk of injury.

The safety attitudes of people who use multi-purpose recreation facilities as a physical activity setting.

2011-06-01

Multi-purpose recreation facilities (MPRFs) are a popular setting for physical activity and it is therefore important that they are safe for all patrons. However, the attitudes of MPRF users towards safety are a potential barrier to the success of injury prevention programmes implemented within MPRFs. This article reports a survey of the safety attitudes of over 700 users of four indoor MPRFs. Factor analysis of 12 five-point Likert scale statements showed that the attitudes clustered around three major dimensions - the importance of safety, the benefits of safety and the perceptions of injury risk. Together, these three dimensions accounted for 49% of the variability in the attitudes. More than 85% of respondents agreed/strongly agreed that: safety was an important aspect of physical activity participation; being injured affected enjoyment of physical activity; people should adopt appropriate safety measures for all physical activity; and individuals were responsible for their own safety. The MPRF users, particularly women and older people, were generally safety conscious, believed in adopting safety measures, and were willing to take responsibility for their own safety. Facility managers can be confident that if they provide evidence-based injury prevention interventions in these settings, then users will respond appropriately and adopt the promoted behaviours.

Direct relationships between safety concerns and physical activity have been inconsistently patterned in the literature. To tease out these relationships, crime, pedestrian, and traffic safety were examined as moderators of built environment associations with physical activity. Exploratory analyses used two cross-sectional studies of 2068 adults ages 20-65 and 718 seniors ages 66+ with similar designs and measures. The studies were conducted in the Baltimore, Maryland-Washington, DC and Seattle-King County, Washington regions during 2001-2005 (adults) and 2005-2008 (seniors). Participants were recruited from areas selected to sample high- and low- income and walkability. Independent variables perceived crime, traffic, and pedestrian safety were measured using scales from validated instruments. A GIS-based walkability index was calculated for a street-network buffer around each participant's home address. Outcomes were total physical activity measured using accelerometers and transportation and leisure walking measured with validated self-reports (IPAQ-long). Mixed effects regression models were conducted separately for each sample. Of 36 interactions evaluated across both studies, only 5 were significant (p< .05). Significant interactions did not consistently support a pattern of highest physical activity when safety was rated high and environments were favorable. There was not consistent evidence that safety concerns reduced the beneficial effects of favorable environments on physical activity. Only pedestrian safety showed evidence of a consistent main effect with physical activity outcomes, possibly because pedestrian safety items (e.g., crosswalks, sidewalks) were not as subjective as those on the crime and traffic safety scales. Clear relationships between crime, pedestrian, and traffic safety with physical activity levels remain elusive.

Safety-Related Concerns of Parents for Children with Disabilities and Chronic Conditions.

2016-01-01

The aim of this study was to explore the safety-related concerns of parents of children with a variety of disabilities and chronic conditions. We sought to examine concerns common to parents as they related to their children's delayed development, behavioral difficulties, and chronic conditions. A qualitative approach guided by grounded theory was used. Participants included parents of children between 1 and 5 years with a disability or chronic condition who resided in British Columbia, Canada. Data were collected using in-depth in-person interviews and analysis conducted using constant comparative methods. Three themes were identified that reflected parental safety concerns. These included concerns about: (1) Child's level of understanding about danger; (2) Child interactions with physical environment (concerns about child movement, concerns about ingestions); (3) Child interactions with social environment. Difficult-to-manage behaviors and cognitive limitations exacerbated parents' safety concerns. Parents were found to share safety concerns about movement and ingestions across a range of types of child health conditions. For themes of child movement and child ingestions, findings supported the utility of a noncategorical approach for the design of injury prevention strategies for these types of concerns. Parent concerns about child lack of understanding about risk and social safety concerns were linked to a smaller number of conditions and supported a more tailored approach. Flexible approaches may be needed that can offer both generic and specific information and to meet the needs of parents and clinicians.

�min/week increase in recreational walking (p = 0.009), however findings for transport walking were non-significant. All associations between suburb-level crime and walking were non-significant. This study provides longitudinal evidence of a potential causal relationship between residents' perceptions of safety from crime and recreational walking. Safety perceptions appeared to influence recreational walking, rather than transport-related walking. Given the popularity of recreational walking and the need to increase levels of physical activity, community social and physical environmental interventions that foster residents' feelings of safety are likely to increase recreational walking and produce public health gains.

Ma, Yonghuan; Niu, Wenyuan; Li, Qianqian

Based on social physics, this paper designs the index system of food safety, builds early warning model of food safety, calculates the degree of food safety, and assesses the state of early warning of 2007 in China. The result shows the degree of food safety is near 0.7 in securer state, belonging to slight emergency. It is much lower in eastern areas of developed regions, belonging to insecure state in the mass. That the food safety is ensured in major grain producing areas, Inner Mongolia, Ningxia and Xinjiang is the prerequisite of realizing the food safety of China. The result also shows four significant indices, grain production capacity, grain circulation order, grain demand and grain supply, which are important indicatio to control food safety.

Characterizing neighborhood environments in relation to physical activity is complex. Latent profiles of parents' perceptions of neighborhood characteristics were examined in relation to accelerometer-measured moderate-to-vigorous physical activity (MVPA) among 678 children (ages 6-12) in two US regions. Neighborhood environment profiles derived from walkability, transit access, aesthetics, crime and traffic safety, pedestrian infrastructure, and recreation/park access were created for each region. The San Diego County profile lowest on walkability and recreation/park access was associated with an average of 13 fewer min/day of children's out-of-school MVPA compared to profiles higher on walkability and recreation/park access. Seattle/King County profiles did not differ on children's MVPA. Neighborhood environment profiles were associated with children's MVPA in one region, but results were inconsistent across regions.

In addition to hazardous conditions that are prevalent in mines, there are various physical and psychosocial risk factors that can affect mine workers' safety and health. Without due diligence to mine safety, these risk factors can affect workers' safety experience, in terms of near misses, disabling injuries and accidents experienced or witnessed by workers. This study sets out to examine the effects of physical and psychosocial risk factors on workers' safety experience in a sample of Ghanaian miners. 307 participants from five mining companies responded to a cross sectional survey examining physical and psychosocial hazards and their implications for employees' safety experience. Zero-inflated Poisson regression models indicated that mining conditions, equipment, ambient conditions, support and security, and work demands and control are significant predictors of near misses, disabling injuries, and accidents experienced or witnessed by workers. The type of mine had important implications for workers' safety experience. Copyright © 2013 Elsevier Ltd and National Safety Council. All rights reserved.

Health promotion strategies grounded by evidence-based determinants of physical activity constitute an important focus of physiotherapy practice in the twenty-first century. This study investigated associations between neighborhood environmental factors and health-related moderate-to-vigorous physical activity (MVPA) and walking for transportation and recreation among community dwelling Nigerian older adults. A representative sample of 353 Nigerian older adults (age = 68.9 ± 9.13 years) in a cross-sectional survey provided self-reported min/week of MVPA and walking for transportation and recreation and perceived neighborhood environmental factors. In multilevel linear regression analyses, proximity of destinations (β = 3.291; CI = 0.392, 6.191), access to services and places (β = 4.417; CI = 0.995, 7.838), esthetics (β = 3.603; CI = 0.617, 6.590), traffic safety (β = 5.685; CI = 3.334, 8.036), and safety from crime (β = 1.717; CI = 0.466, 2.968) were related to more MVPA. Also, proximity of destinations (β = 1.656; CI = 0.022, 3.291) and safety from crime (β = 2.205; CI = 0.018, 4.579) were related to more transport walking. Access to services and places (β = 2.086; CI = 0.713, 3.459) and walking infrastructure and safety (β = 1.741; CI = 0.199, 3.282) were related to more recreational walking. Six of eight supportive environmental factors were associated with more physical activity among community dwelling older Nigerian adults. Policy makers including physiotherapists in this role can use the evidence to inform community-based physical activity and health promotion programs for older adults in Nigeria.

Objective To examine, in a nationally-representative sample of high school students, to what extent one or more additional threats to physical safety exacerbates the risk of sadness and suicidality among victims of school and/or cyber-bullying. Methods National data from the 2015 Youth Risk Behavior Survey (YRBS) were analyzed for grades 9-12 (n = 15,624). Victimization groups were characterized by school-bullying and cyber-bullying, with and without additional threats to physical safety: fighting at school, being threatened/injured at school, and skipping school out of fear for one's safety. Outcomes included 2-week sadness and suicidality. Outcomes for victimization groups were compared to non-victims using logistic regression adjusting for sex, grade and race/ethnicity. Results Overall, 20.2% of students were school-bullied, and 15.5% were cyber-bullied in the past year. Compared to non-victims, victims of school-bullying and victims of cyber-bullying (VoCBs) who did not experience additional threats to physical safety were 2.76 and 3.83 times more likely to report 2-week sadness, and 3.39 and 3.27 times more likely to exhibit suicidality, respectively. Conversely, victims of bullying who experienced one or more additional threats to physical safety were successively more likely to report these adverse outcomes. Notably, victims of school-bullying and VoCBs with all three additional risk factors were 13.13 and 17.75 times more likely to exhibit suicidality, respectively. Conclusion Risk of depression symptoms and suicidality among victims of school-bullying and/or cyber-bullying is greatly increased among those who have experienced additional threats to physical safety: fighting at school, being threatened/injured at school and skipping school out of fear for their safety.

The study aims to explore whether health care professionals' perceptions of patient safety in their practice were associated with the number of patient safety incidents identified in patient records. Seventy primary care practices of general practice, general dental practice, midwifery practices and allied health care practices were used in the study. A retrospective audit of 50 patient records was performed to identify patient safety incidents in each of the practices and a survey among health professionals to identify their perceptions of patient safety. All health professions felt that 'communication breakdowns inside the practice' as well as 'communication breakdowns outside the practice' and 'reporting of patient safety concerns' were a threat to patient safety in their work setting. We found little association between the perceptions of health professionals and the number of safety incidents. The only item with a significant relation to a higher number of safety incidents referred to the perception of 'communication problems outside the practice' as a threat to patient safety. This study indicates that the assessment of professionals' perceptions may be complementary to observed safety incidents, but not linked to an objective measure of patient safety. © 2012 John Wiley & Sons Ltd.

Objective A recent Institute of Medicine report called for attention to safety issues related to electronic health records (EHRs). We analyzed EHR-related safety concerns reported within a large, integrated healthcare system. Methods The Informatics Patient Safety Office of the Veterans Health Administration (VA) maintains a non-punitive, voluntary reporting system to collect and investigate EHR-related safety concerns (ie, adverse events, potential events, and near misses). We analyzed completed investigations using an eight-dimension sociotechnical conceptual model that accounted for both technical and non-technical dimensions of safety. Using the framework analysis approach to qualitative data, we identified emergent and recurring safety concerns common to multiple reports. Results We extracted 100 consecutive, unique, closed investigations between August 2009 and May 2013 from 344 reported incidents. Seventy-four involved unsafe technology and 25 involved unsafe use of technology. A majority (70%) involved two or more model dimensions. Most often, non-technical dimensions such as workflow, policies, and personnel interacted in a complex fashion with technical dimensions such as software/hardware, content, and user interface to produce safety concerns. Most (94%) safety concerns related to either unmet data-display needs in the EHR (ie, displayed information available to the end user failed to reduce uncertainty or led to increased potential for patient harm), software upgrades or modifications, data transmission between components of the EHR, or ‘hidden dependencies’ within the EHR. Discussion EHR-related safety concerns involving both unsafe technology and unsafe use of technology persist long after ‘go-live’ and despite the sophisticated EHR infrastructure represented in our data source. Currently, few healthcare institutions have reporting and analysis capabilities similar to the VA. Conclusions Because EHR-related safety concerns have complex

External forces, such as ground reaction force or air drag acting on athletes' bodies in sports, determine the sport-specific demands on athletes' physical fitness. In order to establish appropriate physical conditioning regimes, which adequately prepare athletes for the loads and physical demands occurring in their sports and help reduce the risk of injury, sport-and/or discipline-specific knowledge of the external forces is needed. However, due to methodological shortcomings in biomechanical research, data comprehensively describing the external forces that occur in alpine super-G (SG) and downhill (DH) are so far lacking. Therefore, this study applied new and accurate wearable sensor-based technology to determine the external forces acting on skiers during World Cup (WC) alpine skiing competitions in the disciplines of SG and DH and to compare these with those occurring in giant slalom (GS), for which previous research knowledge exists. External forces were determined using WC forerunners carrying a differential global navigation satellite system (dGNSS). Combining the dGNSS data with a digital terrain model of the snow surface and an air drag model, the magnitudes of ground reaction forces were computed. It was found that the applied methodology may not only be used to track physical demands and loads on athletes, but also to simultaneously investigate safety aspects, such as the effectiveness of speed control through increased air drag and ski–snow friction forces in the respective disciplines. Therefore, the component of the ground reaction force in the direction of travel (ski–snow friction) and air drag force were computed. This study showed that (1) the validity of high-end dGNSS systems allows meaningful investigations such as characterization of physical demands and effectiveness of safety measures in highly dynamic sports; (2) physical demands were substantially different between GS, SG, and DH; and (3) safety-related reduction of skiing speed might

Previous literature indicates physical activity and obesity are interrelated problems, especially among children in disorganized environments. Qualitative focus groups were conducted with parents of elementary school children located within the Mississippi Delta to answer one overarching research question: "What influence do safety concerns have on physical activity for children in the Mississippi Delta?" There were 2 large themes; first was that recreational areas were criminal and the second was that safety concerns were a barrier to physical activity. Safety concerns as a barrier to physical activity rendered 3 sub-themes, including 1) Parental fear of crime inhibited the use of public recreational spaces, 2) Parental perceptions of police as ineffective and untrustworthy reduced the use of public spaces where children might play, and 3) Parents often expressed safety-induced intense supervision requirements that limited the physical activity of their children. Our study provides valuable insights into the mechanisms by which safety concerns limit physical activity of children in the Mississippi Delta.

2015-02-01

Ionic liquids have been highlighted as non-flammable, environmentally friendly, and suggested as possible solvents in lithium ion battery electrolytes. Here, the application of two ionic liquids from the EMIm-family in a state-of-the-art carbonate solvent based electrolyte is studied with a focus on safety improvement. The impact of the composition on physical and safety related properties is investigated for IL concentrations of additive (∼5 wt%) up to co-solvent concentrations (∼60 wt%). Furthermore, the role of the lithium salt concentration is separately addressed by studying a set of electrolytes at 0.5 M, 1 M, and 2 M LiPF6 concentrations. A large impact on the electrolyte properties is found for the electrolytes containing EMImTFSI and high salt concentrations. The composition 2 M LiPF6 EC:DEC:IL (1:1:3 wt%) is found non-flammable for both choices of ILs added. The macroscopic observations are complemented by a Raman spectroscopy analysis whereby a change in the Li+ solvation is detected for IL concentrations >4.5 mol%.

Sixty-one African American women (ages 20-50 years) from a rural community in Alabama participated in six focus groups. Barriers to and enablers of physical activity were identified and grouped into personal, environmental (social and physical), policy, and cultural themes for qualitative analyses. Personal factors included motivation, perceived health, feeling tired, and lack of time; social environmental factors included support from friends, family, and issues related to child care; physical environmental factors included weather, access to facilities, availability of sidewalks or other places to walk; policy factors included personal safety concerns (loose dogs, traffic, etc.) and inflexible work environments. Some, but not all, women perceived cultural differences as a factor affecting physical activity levels. Differences in socioeconomic levels and time demands among women of different cultures were identified as factors that may influence physical activity. Participants provided suggestions for community-based physical activity interventions using an environmental approach.

A high percentage of all sports injuries occur during school sports. The aim of this study was to collect statements and opinions of sports teachers for safety in physical education. In a cross-sectional study, 296 teachers (202 with, 94 without a teaching qualification in "exercise and sports") at 77 Tyrolean "New Middle Schools" (former secondary schools) were interviewed. They judged various statements on school sports safety using a 5-point verbal rating scale. Irrespective of gender, teachers with a teaching qualification stated significantly more frequently (p = 0.015) that they have participated in continuing education on accident prevention than had their colleagues without qualification. The same applies to the checking of gymnastic and sports equipment before use (p < 0.001) and warming up at the beginning of the lesson (p < 0.001). Female sports teachers allowed their pupils more often (p = 0.002) to participate without adequate sportswear in physical education than did their male counterparts. Of all respondents, 57 % knew about technical faults in sports halls, which have also been reported to the school administration. In more than half (58 %) of these, reported defects were repaired completely and in one-third (36 %), a partial repair was reported. Participants estimated that the major risk for school sports injuries was due to the low motor skills of the pupils, inhomogeneous groups, large numbers of pupils, outdated sports equipment, and ball games. Since about a third of all surveyed teachers had no teaching qualification in exercise and sports, this group should come into the focus of regular continuing education in accident prevention. © Georg Thieme Verlag KG Stuttgart · New York.

This article explores the effects of physically manipulated packaging materials on the quality and safety of meat products. Recently, innovative measures for improving quality and extending the shelf-life of packaged meat products have been developed, utilizing technologies including barrier film, active packaging, nanotechnology, microperforation, irradiation, plasma and far-infrared ray (FIR) treatments. Despite these developments, each technology has peculiar drawbacks which will need to be addressed by meat scientists in the future. To develop successful meat packaging systems, key product characteristics affecting stability, environmental conditions during storage until consumption, and consumers' packaging expectations must all be taken into consideration. Furthermore, the safety issues related to packaging materials must also be taken into account when processing, packaging and storing meat products.

Mine safety assessment using gray relational analysis and bow tie model

PubMed Central

2018-01-01

Mine safety assessment is a precondition for ensuring orderly and safety in production. The main purpose of this study was to prevent mine accidents more effectively by proposing a composite risk analysis model. First, the weights of the assessment indicators were determined by the revised integrated weight method, in which the objective weights were determined by a variation coefficient method and the subjective weights determined by the Delphi method. A new formula was then adopted to calculate the integrated weights based on the subjective and objective weights. Second, after the assessment indicator weights were determined, gray relational analysis was used to evaluate the safety of mine enterprises. Mine enterprise safety was ranked according to the gray relational degree, and weak links of mine safety practices identified based on gray relational analysis. Third, to validate the revised integrated weight method adopted in the process of gray relational analysis, the fuzzy evaluation method was used to the safety assessment of mine enterprises. Fourth, for first time, bow tie model was adopted to identify the causes and consequences of weak links and allow corresponding safety measures to be taken to guarantee the mine’s safe production. A case study of mine safety assessment was presented to demonstrate the effectiveness and rationality of the proposed composite risk analysis model, which can be applied to other related industries for safety evaluation.

Hospital workers are exposed to many occupational hazards that may threaten their health and safety. Physical hazards encountered in hospital working environment include temperature, illumination, noise, electrical injuries, and radiation. To assess the awareness of healthcare workers (HCWs) about physical hazards in Tanta university hospitals, this cross-sectional study included 401 HCWs (physicians, nurses, technicians, and workers) from seven departments (general surgery, orthopedics, radiology, ophthalmology, kitchen, incinerator, and laundry). Data were collected through interview questionnaire to assess six types of physical hazards (noise, electric hazards, temperature, radiation, fire, and lighting,). Most of the physicians (63.7%) were aware of the level of noise. All physicians, nurses, technicians, and majority of workers reported that hearing protective devices were not available, and all HCWs reported that periodic hearing examination was not performed. Most of the nurses (75.2%) and workers (68.5%) did not attended emergency training, and more than two thirds of all HCWs were not briefed about emergency evacuation. Most HCWs were not given appropriate radiation safety training before starting work (88% of workers, 73.7% of nurses, 65.7% of physicians, and 68.3% of technicians). The majority of physicians, nurses, and technicians (70.5, 65.4, and 53.7%) denied regular environmental monitoring for radiation level inside work place. Health education programs on health and safety issues regarding physical hazards should be mandatory to all healthcare workers to improve their awareness and protect them from undue exposures they may face due to lack of adequate awareness and knowledge. There is urgent need of expanding the occupational healthcare services in Egypt to cover all the employees as indicated by the international recommendations and the Egyptian Constitution, legislation, and community necessity.

(1) Background: An increase in or at least the sustainment of walking activities across a wide section of the population is a crucial health-related task for Central and East European countries. The aim of this study was to assess the associations between adolescents’ walking activities and various levels of perceived safety of the built environment in differing socio-demographic backgrounds of Poland and the Czech Republic. Furthermore, we aimed to determine major moderators affecting the walking habits of adolescents in areas with different levels of walkability. (2) Methods: The surveys were conducted during the 2008–2009 and 2013–2014 school years in 24 Polish and 35 Czech secondary schools, with a sample of 2001 adolescents. All participants completed the International Physical Activity Questionnaire–Long Form and the NEWS–Abbreviated. Selected students took part in objective weekly monitoring of physical activity (PA). (3) Results: Boys and girls who perceived their neighborhood environment as the safest were significantly more likely to meet the recommendations for leisure-time walking. Adolescents from the safest environment achieved 11,024 steps/day on average, while those from the least safe environment achieved 9686 steps/day. (4) Conclusions: A safe neighborhood environment significantly predicts walking activities among girls. Environmental safety improvement can support the active transport and better use of leisure time PA. PMID:29329276

This paper describes the implementation of physical safety system for the new low energy electron beam (EB) accelerator installed at Block 43T Nuclear Malaysia. The low energy EB is a locally designed and developed with a target energy of 300 keV. The issues on radiation protection have been addressed by the installation of radiation shielding in the form of a bunker and installation radiation monitors. Additional precaution is needed to ensure that personnel are not exposed to radiation and other physical hazards. Unintentional access to the radiation room can cause serious hazard and hence safety features must be installed to prevent such events. In this work we design and built a control and monitoring system for the shielding door. The system provides signals to the EB control panel to allow or prevent operation. The design includes limit switches, key-activated switches and emergency stop button and surveillance camera. Entry procedure is also developed as written record and for information purposes. As a result, through this safety implementation human error will be prevented, increase alertness during operation and minimizing unnecessary radiation exposure.

The aim of this study was to analyse electronic health record-related patient safety incidents in the patient safety incident reporting database in fully digital hospitals in Finland. We compare Finnish data to similar international data and discuss their content with regard to the literature. We analysed the types of electronic health record-related patient safety incidents that occurred at 23 hospitals during a 2-year period. A procedure of taxonomy mapping served to allow comparisons. This study represents a rare examination of patient safety risks in a fully digital environment. The proportion of electronic health record-related incidents was markedly higher in our study than in previous studies with similar data. Human-computer interaction problems were the most frequently reported. The results show the possibility of error arising from the complex interaction between clinicians and computers.

Objectives We investigated associations of officially recorded crime and perceived neighbourhood safety with physical health, evaluating potential effect modification by gender. Setting Nationally representative population-based survey in New Zealand. Participants Individual-level data from 6995 New Zealand General Social Survey (2010–2011) participants with complete data on physical health status, perceived neighbourhood safety, sociodemographic characteristics and smoking. Crime rate for each participant's home census was estimated based on data from the New Zealand Police (2008–2010). Primary outcome measure The Transformed Physical Composite Score from the SF-12, a physical health summary score based on self-report ranging from 0 to 100. Results We used cluster robust multivariable regression models to examine the associations among neighbourhood crime rates, perceived neighbourhood safety and the physical health summary score. Crime rates predicted adults’ perception that it was unsafe to walk in their neighbourhood at night: for each additional crime per 100 000 residents adults were 1.9% more likely to perceive their neighbourhood as unsafe (95% CI 1.2% to 2.5%). While relatively uncommon, the rate of crime with a weapon strongly predicted perceived safety: for each additional crime per 100 000 residents in this category, adults were 12.9% more likely to report the neighbourhood as unsafe (95% CI 8.8% to 17.0%). Police-recorded violent and night crime rates were associated with worse physical health among women: for each additional crime per 100 000 residents in these category women had a 0.3 point lower physical health score (95% CIs −0.6 to −0.1 for violent crime and −0.5 to −0.1 for crime at night, gender interaction p values 0.08 and 0.01, respectively). Perceiving the neighbourhood as unsafe was independently associated with 1.0 point lower physical health score (95% CI −1.5 to −0.5). Conclusions Gender may modify the

Since the International Conference on Nuclear Criticality Safety (ICNC) 2007, the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) have continued to expand their efforts and broaden their scope. Eighteen countries participated on the ICSBEP in 2007. Now, there are 20, with recent contributions from Sweden and Argentina. The IRPhEP has also expanded from eight contributing countries in 2007 to 16 in 2011. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Criticality Safety Benchmark Experiments1' have increased from 442 evaluations (38000 pages), containing benchmark specifications for 3955 critical ormore » subcritical configurations to 516 evaluations (nearly 55000 pages), containing benchmark specifications for 4405 critical or subcritical configurations in the 2010 Edition of the ICSBEP Handbook. The contents of the Handbook have also increased from 21 to 24 criticality-alarm-placement/shielding configurations with multiple dose points for each, and from 20 to 200 configurations categorized as fundamental physics measurements relevant to criticality safety applications. Approximately 25 new evaluations and 150 additional configurations are expected to be added to the 2011 edition of the Handbook. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments2' have increased from 16 different experimental series that were performed at 12 different reactor facilities to 53 experimental series that were performed at 30 different reactor facilities in the 2011 edition of the Handbook.

The trucking industry has a high burden of work-related injuries. This study examined factors, such as safety climate perceptions, that may impact injury risk. A random sample of 9800 commercial driver's license holders (CDL) were sent surveys, only 4360 were eligible truck drivers. Descriptive statistics and logistic regression models were developed to describe the population and identify variables associated with work-related injury. 2189 drivers completed the pertinent interview questions. Driving less-than-truckload, daytime sleepiness, pressure to work faster, and having a poor composite score for safety perceptions were all associated with increased likelihood of work-related injury. Positive safety perception score was protective for odds of work-related injury, and increased claim filing when injured. Positive psychological safety climate is associated with decreased likelihood of work-related injury and increased likelihood that a driver injured on the job files a workers' compensation claim. © 2017 Wiley Periodicals, Inc.

Techniques related to the use of radiolabeled antibodies in humans are reviewed and evaluated in this report. It is intended as an informational resource for the US Nuclear Regulatory Commission (NRC) and NRC licensees. Descriptions of techniques and health and safety issues are provided. Principal methods for labeling antibodies are summarized to help identify related radiation safety problems in the preparation of dosages for administration to patients. The descriptions are derived from an extensive literature review and consultations with experts in the field. A glossary of terms and acronyms is also included. An assessment was made of the extent ofmore » the involvement of organizations (other than the NRC) with safety issues related to radiolabeled antibodies, in order to identify regulatory issues which require attention. Federal regulations and guides were also reviewed for their relevance. A few (but significant) differences between the use of common radiopharmaceuticals and radiolabeled antibodies were observed. The clearance rate of whole, radiolabeled immunoglobulin is somewhat slower than common radiopharmaceuticals, and new methods of administration are being used. New nuclides are being used or considered (e.g., Re-186 and At-211) for labeling antibodies. Some of these nuclides present new dosimetry, instrument calibration, and patient management problems. Subjects related to radiation safety that require additional research are identified. 149 refs., 3 figs., 20 tabs.« less

2017-01-18

The widespread adoption of health information technology (HIT) has led to new patient safety hazards that are often difficult to identify. Patient safety event reports, which are self-reported descriptions of safety hazards, provide one view of potential HIT-related safety events. However, identifying HIT-related reports can be challenging as they are often categorized under other more predominate clinical categories. This challenge of identifying HIT-related reports is exacerbated by the increasing number and complexity of reports which pose challenges to human annotators that must manually review reports. In this paper, we apply active learning techniques to support classification of patient safety event reports as HIT-related. We evaluated different strategies and demonstrated a 30% increase in average precision of a confirmatory sampling strategy over a baseline no active learning approach after 10 learning iterations.

The US construction industry annually experiences a relatively high rate of fatalities and injuries; therefore, improving safety practices should be considered a top priority for this industry. Modular/prefabricated building construction is a construction strategy that involves manufacturing of the whole building or some of its components off-site. This research focuses on the safety performance of the modular/prefabricated building construction sector during both manufacturing and on-site processes. This safety evaluation can serve as the starting point for improving the safety performance of this sector. Research was conducted based on Occupational Safety and Health Administration investigated accidents. The study found 125 accidents related to modular/prefabricated building construction. The details of each accident were closely examined to identify the types of injury and underlying causes. Out of 125 accidents, there were 48 fatalities (38.4%), 63 hospitalized injuries (50.4%), and 14 non-hospitalized injuries (11.2%). It was found that, the most common type of injury in modular/prefabricated construction was 'fracture', and the most common cause of accidents was 'fall'. The most frequent cause of cause (underlying and root cause) was 'unstable structure'. In this research, the accidents were also examined in terms of corresponding location, occupation, equipment as well as activities during which the accidents occurred. For improving safety records of the modular/prefabricated construction sector, this study recommends that future research be conducted on stabilizing structures during their lifting, storing, and permanent installation, securing fall protection systems during on-site assembly of components while working from heights, and developing training programmes and standards focused on modular/prefabricated construction.

Advanced Test Reactor Safety Basis Upgrade Lessons Learned Relative to Design Basis Verification and Safety Basis Management

DOE Office of Scientific and Technical Information (OSTI.GOV)

G. L. Sharp; R. T. McCracken

The Advanced Test Reactor (ATR) is a pressurized light-water reactor with a design thermal power of 250 MW. The principal function of the ATR is to provide a high neutron flux for testing reactor fuels and other materials. The reactor also provides other irradiation services such as radioisotope production. The ATR and its support facilities are located at the Test Reactor Area of the Idaho National Engineering and Environmental Laboratory (INEEL). An audit conducted by the Department of Energy's Office of Independent Oversight and Performance Assurance (DOE OA) raised concerns that design conditions at the ATR were not adequately analyzedmore » in the safety analysis and that legacy design basis management practices had the potential to further impact safe operation of the facility.1 The concerns identified by the audit team, and issues raised during additional reviews performed by ATR safety analysts, were evaluated through the unreviewed safety question process resulting in shutdown of the ATR for more than three months while these concerns were resolved. Past management of the ATR safety basis, relative to facility design basis management and change control, led to concerns that discrepancies in the safety basis may have developed. Although not required by DOE orders or regulations, not performing design basis verification in conjunction with development of the 10 CFR 830 Subpart B upgraded safety basis allowed these potential weaknesses to be carried forward. Configuration management and a clear definition of the existing facility design basis have a direct relation to developing and maintaining a high quality safety basis which properly identifies and mitigates all hazards and postulated accident conditions. These relations and the impact of past safety basis management practices have been reviewed in order to identify lessons learned from the safety basis upgrade process and appropriate actions to resolve possible concerns with respect to the current ATR

Factors Implicated in Safety-related Firefighter Fatalities.

PubMed

Kahn, Steven A; Palmieri, Tina L; Sen, Soman; Woods, Jason; Gunter, Oliver L

Firefighting is wrought with risk, as 80-100 firefighters (FFs) die on the job each year in the United States. Many of the fatalities have been analyzed by the National Institute for Occupational Safety and Health (NIOSH) to determine contributing factors. The purpose of this study is to determine variables that put FFs at risk for potentially preventable workplace mortality such as use of personal protective equipment (PPE), seat belts, and appropriate training/fitness/clearance for duty. The NIOSH FF Fatality Database reports from 2009 to 2014 were analyzed. Data including age, gender, years on the job, weather, other calls on the same shift, and department type were compared between FFs who employed PPE, seat belts, or wellness/fitness and those who did not. A second group of FFs was determined by NIOSH to have inexperience, lack of training, or inappropriate clearance for duty implicated in their fatalities. Comparisons for the second group were between those whose department used training and safety-related standard operating protocols and those who did not. In 84/176 deaths, PPE/seat belts/fitness was implicated in the fatality. Lack of PPE was more likely on clear days (P = .03) but less likely on cloudy and windy days (P < .001). These FFs dying with lack of PPE had more time on the job in a single department, 18 vs 13 years (P = .03), and more time in a volunteer department, 17 vs 8 years (P < .01). Being deployed on another call during the same shift was associated with lack of PPE-34 vs 16% of those who had not been on another call (P = .005). Lack of training, experience, or medical clearance was implicated in fatalities for 100/176 FFs. FFs who worked in departments that lacked standard operating protocols for respirator fit testing, PPE, fitness testing, rapid intervention, medical clearance, safety/distress alarms, vehicle maintenance, or incident command were statistically more likely to have lack of experience/training/clearance implicated in the

Can Civility Norms Boost Positive Effects of Management Commitment to Safety?

PubMed

McGonagle, Alyssa K; Childress, Niambi M; Walsh, Benjamin M; Bauerle, Timothy J

2016-07-03

We proposed that civility norms would strengthen relationships between management commitment to safety and workers' safety motivation, safety behaviors, and injuries. Survey data were obtained from working adults in hazardous jobs-those for which physical labor is required and/or a realistic possibility of physical injury is present (N = 290). Results showed that management commitment positively related to workers' safety motivation, safety participation, and safety compliance, and negatively related to minor injuries. Furthermore, management commitment to safety displayed a stronger positive relationship with safety motivation and safety participation, and a stronger negative relationship with minor worker injuries when civility norms were high (versus low). The results confirm existing known relationships between management commitment to safety and worker safety motivation and behavior; furthermore, civility norms facilitate the relationships between management commitment to safety and various outcomes important to worker safety. In order to promote an optimally safe working environment, managers should demonstrate a commitment to worker safety and promote positive norms for interpersonal treatment between workers in their units.

Certification of highly complex safety-related systems.

The BIA has now 15 years of experience with the certification of complex electronic systems for safety-related applications in the machinery sector. Using the example of machining centres this presentation will show the systematic procedure for verifying and validating control systems using Application Specific Integrated Circuits (ASICs) and microcomputers for safety functions. One section will describe the control structure of machining centres with control systems using "integrated safety." A diverse redundant architecture combined with crossmonitoring and forced dynamization is explained. In the main section the steps of the systematic certification procedure are explained showing some results of the certification of drilling machines. Specification reviews, design reviews with test case specification, statistical analysis, and walk-throughs are the analytical measures in the testing process. Systematic tests based on the test case specification, Electro Magnetic Interference (EMI), and environmental testing, and site acceptance tests on the machines are the testing measures for validation. A complex software driven system is always undergoing modification. Most of the changes are not safety-relevant but this has to be proven. A systematic procedure for certifying software modifications is presented in the last section of the paper.

Creating an Oversight Infrastructure for Electronic Health Record-Related Patient Safety Hazards

PubMed Central

Singh, Hardeep; Classen, David C.; Sittig, Dean F.

2013-01-01

Electronic health records (EHRs) have potential quality and safety benefits. However, reports of EHR-related safety hazards are now emerging. The Office of the National Coordinator (ONC) for Health Information Technology (HIT) recently sponsored an Institute of Medicine committee to evaluate how HIT use affects patient safety. In this paper, we propose the creation of a national EHR oversight program to provide dedicated surveillance of EHR-related safety hazards and to promote learning from identified errors, close calls, and adverse events. The program calls for data gathering, investigation/analysis and regulatory components. The first two functions will depend on institution-level EHR safety committees that will investigate all known EHR-related adverse events and near-misses and report them nationally using standardized methods. These committees should also perform routine safety self-assessments to proactively identify new risks. Nationally, we propose the long-term creation of a centralized, non-partisan board with an appropriate legal and regulatory infrastructure to ensure the safety of EHRs. We discuss the rationale of the proposed oversight program and its potential organizational components and functions. These include mechanisms for robust data collection and analyses of all safety concerns using multiple methods that extend beyond reporting; multidisciplinary investigation of selected high-risk safety events; and enhanced coordination with other national agencies in order to facilitate broad dissemination of hazards information. Implementation of this proposed infrastructure can facilitate identification of EHR-related adverse events and errors and potentially create a safer and more effective EHR-based health care delivery system.

The increasing number of older adults with blood-related disorders and the introduction of reduced-intensity conditioning regimens has led to increases in hematopoietic stem cell (HSC) transplantation among older adults and a corresponding increase in the age of siblings who donate HSCs to these patients. Data regarding the donation-related experiences of older donors are lacking. The Related Donor Safety Study aimed to examine/compare health-related quality of life (HRQoL) of older versus younger HSC donors. Sixty peripheral blood stem cell (PBSC) donors ages 18 to 60 years and 104 PBSC donors age >60 years completed validated questionnaires before donation and 4 weeks and 1 year after donation. Before donation, older donors had poorer general physical health (t = -3.27; P = .001) but better mental health (t = 2.11; P < .05). There were no age differences in multiple other donation-related factors. At 4 weeks after donation, there were no group differences in general physical/mental health, but older donors were less likely to report donation-related pain (t = -2.26; P < .05) and concerns (t = -3.38; P = .001). At both 4 weeks and 1 year after donation, there were no significant differences in the percentage of each age group feeling physically back to normal or in the number of days it took donors to feel completely well. There was no evidence that increasing age within the older donor group was associated with poorer donation-related HRQoL. Taken together, these data support the current practice of HSC donation by sibling donors above age 60, providing no evidence of worsening HRQoL up to 1 year after donation in individuals up to age 76.

The influence of the physical environment on patient falls has not been fully explored in psychiatric units, despite this patient population's vulnerability and the critical role of the physical environment in patient safety. The research objective is to describe the spatial and temporal pattern of falls occurrences and their location in relation to the levels of safety continuum model. This article presents an exploratory case study design. Seven years of retrospective data on patient falls, yielding 818 sentinel events, in an 81-bed psychiatric hospital in the United States were collected and analyzed. Data focused on extrinsic factors for falls, emphasizing the physical environment. Through a content analysis of the sentinel event narratives, recorded by the hospital staff, this study explored patient falls related to location and elements of the physical environment. The analysis revealed that 15% of recorded falls were attributed to some aspect of or element within the physical environment. The most typical locations of falls were patient rooms (39%), patient bathrooms (22%), and dayrooms (20%). Also, the results identified patterns of environmental factors that appeared linked to increasing patients' susceptibility to falls. Risk factors included poor nighttime lighting, flooring surfaces that were uneven, and spaces that inadvertently limited visual access and supervision. The physical environment plays an often-unexamined role in fall events and specific locations. These results are deserving of further research on design strategies and applications to reduce patient falls in psychiatric hospital settings.

Distinguishing between relational and physical aggression has become a key feature of many developmental studies in North America and Western Europe, but very little information is available on relational aggression in more diverse cultural contexts. This study examined the factor structure of, gender differences in, and associations between relational and physical aggression in China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Children ages 7 to 10 years (N = 1410) reported on their relationally and physically aggressive behavior. Relational and physical aggression shared a common factor structure across countries. Unsurprisingly, boys reported being more physically aggressive than girls across all nine countries; surprisingly, there were no significant gender differences in relational aggression. In all nine countries, relational and physical aggression were significantly correlated (average r = .49). The countries differed significantly in the mean levels of both relational and physical aggression that children reported using and with respect to whether children reported using more physical than relational aggression or more relational than physical aggression. Despite mean level differences in relational and physical aggression across countries, the findings provided support for cross-country similarities in associations between relational and physical aggression, as well as links between gender and aggression.

2016-01-01

Introduction: Work-related traumatic brain injury (TBI) caused by falls is a catastrophic event that leads to disabilities and high socio-medical costs. This study aimed to measure the magnitude of the preventive effect of safety helmets on clinical outcomes and to compare the effect across different heights of fall. Methods: We collected a nationwide, prospective database of work-related injury patients who visited the 10 emergency departments between July 2010 and October 2012. All of the adult patients who experienced work-related fall injuries were eligible, excluding cases with unknown safety helmet use and height of fall. Primary and secondary endpoints were intracranial injury and in-hospital mortality. We calculated adjusted odds ratios (AORs) of safety helmet use and height of fall for study outcomes, and adjusted for any potential confounders. Results: A total of 1298 patients who suffered from work-related fall injuries were enrolled. The industrial or construction area was the most common place of fall injury occurrence, and 45.0% were wearing safety helmets at the time of fall injuries. The safety helmet group was less likely to have intracranial injury comparing with the no safety helmet group (the adjusted odds ratios (ORs) (95% confidence interval (CI)): 0.42 (0.24–0.73)), however, there was no statistical difference of in-hospital mortality between two groups (the adjusted ORs (95% CI): 0.83 (0.34–2.03). In the interaction analysis, preventive effects of safety helmet on intracranial injury were significant within 4 m height of fall. Conclusions: A safety helmet is associated with prevention of intracranial injury resulting from work-related fall and the effect is preserved within 4 m height of fall. Therefore, wearing a safety helmet can be an intervention for protecting fall-related intracranial injury in the workplace. PMID:27801877

Work stress and patient safety: observer-rated work stressors as predictors of characteristics of safety-related events reported by young nurses.

PubMed

Elfering, A; Semmer, N K; Grebner, S

This study investigates the link between workplace stress and the 'non-singularity' of patient safety-related incidents in the hospital setting. Over a period of 2 working weeks 23 young nurses from 19 hospitals in Switzerland documented 314 daily stressful events using a self-observation method (pocket diaries); 62 events were related to patient safety. Familiarity of safety-related events and probability of recurrence, as indicators of non-singularity, were the dependent variables in multilevel regression analyses. Predictor variables were both situational (self-reported situational control, safety compliance) and chronic variables (job stressors such as time pressure, or concentration demands and job control). Chronic work characteristics were rated by trained observers. The most frequent safety-related stressful events included incomplete or incorrect documentation (40.3%), medication errors (near misses 21%), delays in delivery of patient care (9.7%), and violent patients (9.7%). Familiarity of events and probability of recurrence were significantly predicted by chronic job stressors and low job control in multilevel regression analyses. Job stressors and low job control were shown to be risk factors for patient safety. The results suggest that job redesign to enhance job control and decrease job stressors may be an important intervention to increase patient safety.

The number of nuclear safety related equipment suppliers and the availability of spare and replacement parts designed specifically for nuclear safety related application are shrinking rapidly. These have made it necessary for utilities to apply commercial grade spare and replacement parts in nuclear safety related applications after implementing proper acceptance and dedication process to verify that such items conform with the requirements of their use in nuclear safety related application. The general guidelines for the commercial grade item (CGI) acceptance and dedication are provided in US Nuclear Regulatory Commission (NRC) Generic Letters and Electric Power Research Institute (EPRI) Report NP-5652,more » Guideline for the Utilization of Commercial Grade Items in Nuclear Safety Related Applications. This paper presents an application of these generic guidelines for procurement, acceptance, and dedication of a commercial grade generator for use as a standby generator at Salem Generating Station Units 1 and 2. The paper identifies the critical characteristics of the generator which once verified, will provide reasonable assurance that the generator will perform its intended safety function. The paper also delineates the method of verification of the critical characteristics through tests and provide acceptance criteria for the test results.

Examine associations between worksite physical activity promotion strategies and employees' physical activity and sedentary behaviors. Cross-sectional. Seattle-King County, Washington and Baltimore, Maryland-Washington, D.C. regions. Adults working outside the home (n = 1313). Mean age was 45 ± 10 years, 75.8% of participants were non-Hispanic white, 56% were male, and 51% had income ≥$70,000/year. Participants reported demographic characteristics and presence/absence of nine physical activity promotion environment and policy strategies in their work environment (e.g., showers, lockers, physical activity programs). A worksite physical activity promotion index was a tally of strategies. Total sedentary and moderate-to-vigorous physical activity (MVPA) min/d were objectively assessed via 7-day accelerometry. Total job-related physical activity minutes and recreational physical activity minutes were self-reported with the International Physical Activity Questionnaire. Mixed-effects models and generalized estimating equations evaluated the association of the worksite promotion index with physical activity and sedentary behavior, adjusting for demographics. A higher worksite promotion index was significantly associated with higher total sedentary behavior (β = 3.97), MVPA (β = 1.04), recreational physical activity (β = 1.1 and odds ratio = 1.39; away from work and at work, respectively) and negatively with job-related physical activity (β = .90). Multiple worksite physical activity promotion strategies based on environmental supports and policies may increase recreational physical activity and should be evaluated in controlled trials. These findings are particularly important given the increasingly sedentary nature of employment.

Machine learning algorithms increasingly influence our decisions and interact with us in all parts of our daily lives. Therefore, just as we consider the safety of power plants, highways, and a variety of other engineered socio-technical systems, we must also take into account the safety of systems involving machine learning. Heretofore, the definition of safety has not been formalized in a machine learning context. In this article, we do so by defining machine learning safety in terms of risk, epistemic uncertainty, and the harm incurred by unwanted outcomes. We then use this definition to examine safety in all sorts of applications in cyber-physical systems, decision sciences, and data products. We find that the foundational principle of modern statistical machine learning, empirical risk minimization, is not always a sufficient objective. We discuss how four different categories of strategies for achieving safety in engineering, including inherently safe design, safety reserves, safe fail, and procedural safeguards can be mapped to a machine learning context. We then discuss example techniques that can be adopted in each category, such as considering interpretability and causality of predictive models, objective functions beyond expected prediction accuracy, human involvement for labeling difficult or rare examples, and user experience design of software and open data.

Associations of adult physical activity with perceived safety and police-recorded crime: the Multi-ethnic Study of Atherosclerosis

PubMed Central

2012-01-01

Background Due to the inconsistent findings of prior studies, we explored the association of perceived safety and police-recorded crime measures with physical activity. Methods The study included 818 Chicago participants of the Multiethnic Study of Atherosclerosis 45 to 84 years of age. Questionnaire-assessed physical activity included a) transport walking; b) leisure walking; and c) non-walking leisure activities. Perceived safety was assessed through an interviewer-administered questionnaire. Police-recorded crime was assessed through 2-year counts of selected crimes (total and outdoor incivilities, criminal offenses, homicides) per 1000 population. Associations were examined using generalized estimating equation logistic regression models. Results Perceiving a safer neighborhood was positively associated with transport walking and perceiving lower violence was associated with leisure walking. Those in the lowest tertile of total or outdoor incivilities were more likely to report transport walking. Models with both perceived safety and police-recorded measures of crime as independent variables had superior fit for both transport walking and leisure walking outcomes. Neither perceived safety nor police-recorded measures of crime were associated with non-walking leisure activity. Conclusions Perceived and police-recorded measures had independent associations with walking and both should be considered in assessing the impact of neighborhood crime on physical activity.

This cross sectional study aims to determine the effects of gender and parental perception of safety at school on children's physical activity (PA) levels. Parents of school aged Mexican children residing in Guadalajara, Mexico City, and Puerto Vallarta, completed surveys about their children's PA measures. The physical activity indicators were evaluated using linear and logistical regression models. Analysis did not indicate that gender moderated the relationship between parental perception of safety and PA measures, but significant gender issues exist with girls participating less than boys in the three measures of PA in this study (p<0.001). Results suggest the need for additional interventions promoting physical activity in girls in Mexico.

Previous research demonstrates that workplace bullying impacts the welfare of victimized employees, with further consequences for the organization and profession. There is, however, a paucity of information relating to the bullying directed at risk and safety professionals. The present study was conducted to address this issue. Risk and safety professionals (N=420) completed the Negative Acts Questionnaire - Revised and Brief Cope, and reported the extent to which they had been pressured to make or amend a risk or safety based decision. Those experiencing workplace bullying were more likely to engage in a range of coping behaviors, with exposure to work-related and personal bullying particularly influential. Workplace bullying also predicted pressure to make or change a risk or safety based decision. Work related and physically intimidating bullying were particularly important for this aspect of professional practice. Findings are discussed with regard to current practice and the support available to risk and safety professionals. Risk and safety professionals require additional support in relation to workplace bullying and specifically guidance to resist pressure to make or change a risk or safety based decision.

This study aimed to evaluate parental perception of neighbourhood environments and safety in association with children's physical activity among primary school children in Klang, Selangor, Malaysia. A total of 250 children (9-12 years of age) and their parents participated in this cross-sectional study. Physical Activity Questionnaire for Older Children and Neighbourhood Environmental Walkability Scale as well as questions on constrained behaviours (avoidance and defensive behaviours) were used to assess the children's physical activity and parental perception of neighbourhood environment and safety, respectively. More than one-third (36.0%) of the children were physically inactive compared with only a small percentage (4.8%) who were physically active, with boys achieving higher physical activity levels than girls (t = 2.564, P = 0.011). For the environmental scale, parents' perception of land-use mix (access) (r = 0.173, P = 0.006), traffic hazards (r = -0.152, P = 0.016) and defensive behaviour (r = -0.024, P = 0.143) correlated significantly with children's physical activity. In multiple linear regression analysis, child's gender (β = -0.226; P = 0.003), parent's education (β = 0.140; P = 0.001), household income (β = 0.151; P = 0.024), land-use mix (access) (β = 0.134; P = 0.011) and defensive behaviour (β = -0.017; P = 0.038) were significantly associated with physical activity in children (R = 0.349, F = 6.760; P < 0.001), contributing 12.2% of the variances in physical activity of the children. Results highlight the links between parental perception of neighbourhood environments, safety and constrained behaviours with their children's participation in active play. Interventions aimed to increase actual and perceived safety and reduce perceptions of risk by parents in safe neighbourhoods can be targeted to increase children's physical activity in their local

Safety surrogate histograms (SSH): A novel real-time safety assessment of dilemma zone related conflicts at signalized intersections.

PubMed

Ghanipoor Machiani, Sahar; Abbas, Montasir

2016-11-01

Drivers' indecisiveness in dilemma zones (DZ) could result in crash-prone situations at signalized intersections. DZ is to the area ahead of an intersection in which drivers encounter a dilemma regarding whether to stop or proceed through the intersection when the signal turns yellow. An improper decision to stop by the leading driver, combined with the following driver deciding to go, can result in a rear-end collision, unless the following driver recognizes a collision is imminent and adjusts his or her behavior at or shortly after the onset of yellow. Considering the significance of DZ-related crashes, a comprehensive safety measure is needed to characterize the level of safety at signalized intersections. In this study, a novel safety surrogate measure was developed utilizing real-time radar field data. This new measure, called safety surrogate histogram (SSH), captures the degree and frequency of DZ-related conflicts at each intersection approach. SSH includes detailed information regarding the possibility of crashes, because it is calculated based on the vehicles conflicts. An example illustrating the application of the new methodology at two study sites in Virginia is presented and discussed, and a comparison is provided between SSH and other DZ-related safety surrogate measures mentioned in the literature. The results of the study reveal the efficacy of the SSH as complementary to existing surrogate measures. Copyright © 2015 Elsevier Ltd. All rights reserved.

We describe herein, limitations on research at biosafety level 4 (BSL-4) containment laboratories, with regard to biosecurity regulations, safety considerations, research space limitations, and physical constraints in executing experimental procedures. These limitations can severely impact the number of collaborations and size of research projects investigating microbial pathogens of biodefense concern. Acquisition, use, storage, and transfer of biological select agents and toxins (BSAT) are highly regulated due to their potential to pose a severe threat to public health and safety. All federal, state, city, and local regulations must be followed to obtain and maintain registration for the institution to conduct research involving BSAT. These include initial screening and continuous monitoring of personnel, controlled access to containment laboratories, accurate and current BSAT inventory records. Safety considerations are paramount in BSL-4 containment laboratories while considering the types of research tools, workflow and time required for conducting both in vivo and in vitro experiments in limited space. Required use of a positive-pressure encapsulating suit imposes tremendous physical limitations on the researcher. Successful mitigation of these constraints requires additional time, effort, good communication, and creative solutions. Test and evaluation of novel vaccines and therapeutics conducted under good laboratory practice (GLP) conditions for FDA approval are prioritized and frequently share the same physical space with important ongoing basic research studies. The possibilities and limitations of biomedical research involving microbial pathogens of biodefense concern in BSL-4 containment laboratories are explored in this review.

2014-01-01

Current and future aviation safety trends related to the National Aeronautics and Space Administration's Atmospheric Environment Safety Technologies Project's three technical challenges (engine icing characterization and simulation capability; airframe icing simulation and engineering tool capability; and atmospheric hazard sensing and mitigation technology capability) were assessed by examining the National Transportation Safety Board (NTSB) accident database (1989 to 2008), incidents from the Federal Aviation Administration (FAA) accident/incident database (1989 to 2006), and literature from various industry and government sources. The accident and incident data were examined for events involving fixed-wing airplanes operating under Federal Aviation Regulation (FAR) Parts 121, 135, and 91 for atmospheric conditions related to airframe icing, ice-crystal engine icing, turbulence, clear air turbulence, wake vortex, lightning, and low visibility (fog, low ceiling, clouds, precipitation, and low lighting). Five future aviation safety risk areas associated with the three AEST technical challenges were identified after an exhaustive survey of a variety of sources and include: approach and landing accident reduction, icing/ice detection, loss of control in flight, super density operations, and runway safety.

Statistics-related and reliability-physics-related failure processes in electronics devices and products

NASA Astrophysics Data System (ADS)

Suhir, E.

2014-05-01

The well known and widely used experimental reliability "passport" of a mass manufactured electronic or a photonic product — the bathtub curve — reflects the combined contribution of the statistics-related and reliability-physics (physics-of-failure)-related processes. When time progresses, the first process results in a decreasing failure rate, while the second process associated with the material aging and degradation leads to an increased failure rate. An attempt has been made in this analysis to assess the level of the reliability physics-related aging process from the available bathtub curve (diagram). It is assumed that the products of interest underwent the burn-in testing and therefore the obtained bathtub curve does not contain the infant mortality portion. It has been also assumed that the two random processes in question are statistically independent, and that the failure rate of the physical process can be obtained by deducting the theoretically assessed statistical failure rate from the bathtub curve ordinates. In the carried out numerical example, the Raleigh distribution for the statistical failure rate was used, for the sake of a relatively simple illustration. The developed methodology can be used in reliability physics evaluations, when there is a need to better understand the roles of the statistics-related and reliability-physics-related irreversible random processes in reliability evaluations. The future work should include investigations on how powerful and flexible methods and approaches of the statistical mechanics can be effectively employed, in addition to reliability physics techniques, to model the operational reliability of electronic and photonic products.

To develop a goal-oriented praxis theory for enabling safety for relatives when an adult or older patient is close to end-of-life. This is the second part of a project focusing on the situation and needs of relatives in end-of-life care. Our interpretation of the existing corpus of knowledge pertaining to the needs of close relatives in this situation showed the significance of relatives' need for safety. The theory was developed step-by-step, through triangulation of critical review of empirical research in the field, our own clinical experiences from end-of-life care, renewed literature searches and theoretical reasoning. The foundation for the theory is taken from the ethical intention of the philosopher Paul Ricoeur. From this, the theory focuses on relatives in the context of end-of-life care with the goal of enabling safety. This is proposed by four aphorisms functioning as safety enablers and these are directed towards the professional's approach and attitude, the relative's concern for the patient, the specific situation for the relative and the patient's end-of-life period as a period in the life of the relative. Implications for end-of-life practice are considered and include aspects for promotion of just institutions in end-of-life care, the significance of negotiated partnership in end-of-life care, enabling safety for relatives living in existential and practical uncertainty in connection with end-of-life care and diversity of relatives' preferences as they live through this particular period.

The three Rs of fire safety, emergency action, and fire prevention planning: promoting safety at the worksite.

Thompson, Marcella R

2003-04-01

Fire safety is of paramount importance for everyone. In many workplaces, the occupational health nurse's scope of practice encompasses safety related activities. Included within this role is the responsibility for fire safety, emergency action, and fire prevention planning. The Three Rs of fire safety, emergency action, and fire prevention plans are rules, responsibilities, and resources. Myriad building and fire safety codes, regulations, and standards exist with which an employer must comply. An employer's responsibility for installing, testing, inspecting, and maintaining fire safety related equipment is extensive. Emergency action and fire prevention planning begins with conducting a detailed physical survey and preparing site maps. It includes making key policy decisions, writing procedures, and training employees in those procedures by practicing and executing site drills. The best resources available for emergency planning are the local fire department and the property insurer. Planning ahead means an efficient emergency response if disaster strikes. It saves lives, limits property damage, and preserves the environment.

Evaluating North Carolina Food Pantry Food Safety-Related Operating Procedures.

Chaifetz, Ashley; Chapman, Benjamin

2015-11-01

Almost one in seven American households were food insecure in 2012, experiencing difficulty in providing enough food for all family members due to a lack of resources. Food pantries assist a food-insecure population through emergency food provision, but there is a paucity of information on the food safety-related operating procedures used in the pantries. Food pantries operate in a variable regulatory landscape; in some jurisdictions, they are treated equivalent to restaurants, while in others, they operate outside of inspection regimes. By using a mixed methods approach to catalog the standard operating procedures related to food in 105 food pantries from 12 North Carolina counties, we evaluated their potential impact on food safety. Data collected through interviews with pantry managers were supplemented with observed food safety practices scored against a modified version of the North Carolina Food Establishment Inspection Report. Pantries partnered with organized food bank networks were compared with those that operated independently. In this exploratory research, additional comparisons were examined for pantries in metropolitan areas versus nonmetropolitan areas and pantries with managers who had received food safety training versus managers who had not. The results provide a snapshot of how North Carolina food pantries operate and document risk mitigation strategies for foodborne illness for the vulnerable populations they serve. Data analysis reveals gaps in food safety knowledge and practice, indicating that pantries would benefit from more effective food safety training, especially focusing on formalizing risk management strategies. In addition, new tools, procedures, or policy interventions might improve information actualization by food pantry personnel.

Comparative Safety and Tolerability of Anti-VEGF therapy in Age-Related Macular Degeneration

Modi, Yasha S.; Tanchon, Carley; Ehlers, Justis P

2015-01-01

Neovascular age-related macular degeneration (NVAMD) is one of the leading causes of blindness. Over the last decade, the treatment of NVAMD has been revolutionized by the development intravitreal anti-vascular endothelial growth factor (VEGF) therapies. Several anti-VEGF medications are used for the treatment of NVAMD. The safety and tolerability of these medications deserve review given the high prevalence of NVAMD and the significant utilization of these medications. Numerous large randomized clinical trials have not shown any definitive differential safety relative to ocular or systemic safety of these medications. Intravitreal anti-VEGF therapy does appear to impact systemic VEGF levels, but the implications of these changes remain unclear. One unique safety concern relates drug compounding and the potential risks of contamination, specifically for bevacizumab. Continued surveillance for systemic safety concerns, particularly for rare events is merited. Overall these medications are well tolerated and effective in the treatment of NVAMD. PMID:25700714

Maltais, Désirée B.; Wiart, Lesley; Fowler, Eileen; Verschuren, Olaf; Damiano, Diane L.

2014-01-01

Low levels of physical activity are a global health concern for all children. Children with cerebral palsy have even lower physical activity levels than their typically developing peers. Low levels of physical activity, and thus an increased risk for related chronic diseases, are associated with deficits in health-related physical fitness. Recent research has provided therapists with the resources to effectively perform physical fitness testing and physical activity training in clinical settings with children who have cerebral palsy, although most testing and training data to date pertains to those who walk. Nevertheless, based on the present evidence, all children with cerebral palsy should engage, to the extent they are able, in aerobic, anaerobic and muscle strengthening activities. Future research is required to determine the best ways to evaluate health-related physical fitness in non-ambulatory children with cerebral palsy and foster long-term changes in physical activity behavior in all children with this condition.

Sittig, Dean F; Singh, Hardeep

2013-01-01

Although electronic health records (EHRs) have a significant potential to improve patient safety, EHR-related safety concerns have begun to emerge. Based on 369 responses to a survey sent to the memberships of the American Society for Healthcare Risk Management and the American Health Lawyers Association and supplemented by our previous work in EHR-related patient safety, we identified the following common EHR-related safety concerns: (1) incorrect patient identification; (2) extended EHR unavailability (either planned or unplanned); (3) failure to heed a computer-generated warning or alert; (4) system-to-system interface errors; (5) failure to identify, find, or use the most recent patient data; (6) misunderstandings about time; (7) incorrect item selected from a list of items; and (8) open or incomplete orders. In this article, we present a "red-flag"-based approach that can be used by risk managers to identify potential EHR safety concerns in their institutions. An organization that routinely conducts EHR-related surveillance activities, such as the ones proposed here, can significantly reduce risks associated with EHR implementation and use. © 2013 American Society for Healthcare Risk Management of the American Hospital Association.

To explore the safety risks associated with physical interactions between patients and caregivers during treatment and care delivery in Home Care settings. Seven-stage framework from the PRISMA statement for research question, eligibility (definition), search, identification of relevant papers from title and abstract, selection and retrieval of papers, appraisal and synthesis. British Nursing Index (BNI), Allied and Complementary Medicine Database (AMED), Applied Social Sciences Index and Abstracts (ASSIA), Cinahl, Cochrane Library, Embase, Ergonomics Abstracts, Health Business Elite, Health Management Information Consortium (HMIC), Medline, PsycInfo, Scopus, Social Care online, Social Science Citation Index. The included references (n=42) were critically appraised using a modified version of Downs and Black checklist and the Mixed Methods Appraisal Tool. The risk factors are reported using the modified model of human factors of health care in the home to represent the roles of both patients and caregivers in the system. The results are grouped as environment (health policy, physical and social), artefacts (equipment and technology), tasks (procedures and work schedules) and care recipient/provider. These include permanent and temporary building design and access, communication and lone working, provision of equipment and consumables, and clinical tasks. The topics with strong evidence from at least 2 papers relate to risks associated with awkward working positions, social environment issues (additional tasks and distractions), abuse and violence, inadequate team (peer) support, problems with workload planning, needle stick injuries and physical workload (moving and handling patients). As home care increases, there is a need to ensure the safety of both patients and caregivers with an understanding of the physical interactions and tasks to manage safety risks and plan safer care delivery systems.

To understand the perceptions of physical activity-related built environment among urban adults in Hangzhou. A face-to-face interview was conducted among the urban residents aged 25-59 years selected through multistage stratified random sampling in Hangzhou in 2012. The Neighborhood Environment Walkability Scale-Abbreviated (NEWS-A) was used to assess the perception of built environment among residents, including residential building density, the diversities of stores, facilities and others, the accessibility to public service, the street connectivity, walking/cycling facilities, aesthetics, traffic safety, and public security. The multilevel logistic regression model was used to assess the demographic characteristics, BMI and other factors' influence on people's perceptions. Among 1 362 local residents surveyed, no sex, martial status and occupation specific significant differences in the perception of built environment were found. After adjusting other factors, the age group 45-59 years was positively related to the score of street connectivity (OR=2.02, 95% CI: 1.30-3.15). The educational level of college or higher was positively associated with the score of residential building density (OR=1.97, 95% CI: 1.29-3.00) but negatively associated with the score of facility variety (OR=0.65, 95% CI: 0.43-0.97). Overweight or obesity was negatively related to the scores of walking/cycling ways (OR=0.67, 95%CI: 0.48-0.95) and public security (OR=0.75, 95% CI: 0.57-0.99). Compared with the class I residential area, the people in class III residential area had lower perception scores on facility diversity (OR=0.11, 95% CI: 0.04-0.30), accessibility to public service (OR=0.33, 95% CI: 0.11-0.95), street connectivity (OR=0.30, 95% CI: 0.11-0.86) and traffic safety (OR=0.39, 95% CI: 0.17-0.91). The perceptions of physical activity-related built environment was associated with age, educational level, BMI and residential area. The personal characteristics should be considered

Eyler, Amy A; Vest, Joshua R

2002-01-01

Physical activity is an important aspect of health promotion and disease prevention. However, women often have lower rates of physical activity than men. The purpose of this study was to identify environmental and policy determinants to physical activity among rural white women. Six focus groups were conducted with women aged 20-50 years who were not currently regular exercisers. Women reported that the social environment had a strong impact on physical activity level. Factors of the social environment included guilt, family responsibility, and social support. Environmental and policy barriers such as lack of access to places to exercise and safety concerns were also discussed. Intervention suggestions included family exercise and work-site programs. Information gained from this study can be used to fuel further research and inform future physical activity interventions.

Using minority stress theory, the authors investigated risk behaviors of transgender women (trans women) in Lebanon. Using semistructured interviews, the authors explored six areas: relationships with family and friends; openness about gender and sexuality; experiences with stigma; sexual behavior; attitudes and behaviors regarding HIV testing; and perceived HIV-related norms among transgender peers. Participants voiced the importance of different forms of safety: social/emotional, physical, sexual, and financial. Strategies for obtaining safety were negotiated differently depending on social, behavioral, and structural factors in the environment. In this article, we provide study findings from the perspectives of trans women, their exposure to stigma, and the necessary navigation of environments characterized by transphobia.

Screening Electronic Health Record-Related Patient Safety Reports Using Machine Learning.

Marella, William M; Sparnon, Erin; Finley, Edward

2017-03-01

The objective of this study was to develop a semiautomated approach to screening cases that describe hazards associated with the electronic health record (EHR) from a mandatory, population-based patient safety reporting system. Potentially relevant cases were identified through a query of the Pennsylvania Patient Safety Reporting System. A random sample of cases were manually screened for relevance and divided into training, testing, and validation data sets to develop a machine learning model. This model was used to automate screening of remaining potentially relevant cases. Of the 4 algorithms tested, a naive Bayes kernel performed best, with an area under the receiver operating characteristic curve of 0.927 ± 0.023, accuracy of 0.855 ± 0.033, and F score of 0.877 ± 0.027. The machine learning model and text mining approach described here are useful tools for identifying and analyzing adverse event and near-miss reports. Although reporting systems are beginning to incorporate structured fields on health information technology and the EHR, these methods can identify related events that reporters classify in other ways. These methods can facilitate analysis of legacy safety reports by retrieving health information technology-related and EHR-related events from databases without fields and controlled values focused on this subject and distinguishing them from reports in which the EHR is mentioned only in passing. Machine learning and text mining are useful additions to the patient safety toolkit and can be used to semiautomate screening and analysis of unstructured text in safety reports from frontline staff.

Residents of more socioeconomically disadvantaged neighborhoods are more likely to report poorer physical function, although the reasons for this remain unknown. It is possible that neighborhood-level perceptions of safety from crime contribute to this relationship through its association with walking for recreation. Data were obtained from the fourth wave (collected in 2013) of the HABITAT (How Areas in Brisbane Influence HealTh and AcTivity) multilevel longitudinal study of middle- to older-aged adults (46-74 y) residing in 200 neighborhoods in Brisbane, Australia. The data were analyzed separately for men (n = 2190) and women (n = 2977) using multilevel models. Residents of the most disadvantaged neighborhoods had poorer physical function, perceived their neighborhoods to be less safe from crime, and do less walking for recreation. These factors accounted for differences in physical function between disadvantaged and advantaged neighborhoods (24% for men and 25% for women). This study highlights the importance of contextual characteristics, through their associations with behaviors, that can have in explaining the relationship between neighborhood disadvantage and physical function. Interventions aimed at improving neighborhood safety integrated with supportive environments for physical activity may have positive impact on physical function among all socioeconomic groups.

Physical activity (PA) promotion is beneficial to gain and maintain optimal health, but might increase risks for physical activity-related injury (PARI). This cross-sectional study aimed to investigate the incidence rate and identify risk factors of PARI among Chinese middle school students. Selected via the method of cluster random sampling, students graded 7⁻8 (junior) and 10⁻11 (senior) from five middle schools (aged from 10 to 18 years old) in Shantou were invited to participate in the survey. Information on socio-demography, PA involvement, sleep duration, individual safety awareness and exercise behavior, and PARI experiences in the past 12 month was collected. Multivariate logistic regression model was performed to estimate the risk factors of PARI. A total of 3082 participants completed the valid questionnaires, with an overall incidence rate of 25.1%. Boys, junior school students, sports team members, and those with lower safety awareness, living with single parent, and without any chronic conditions were at higher risks for PARI. Moreover, exercising on wet floor or with illness frequently would also be more likely to experience injury, especially those with at least 120 min per day. In conclusion, PARI was prevalent among middle school students in southern China. The above data provide insights that were focused and effective actions should be taken to prevent school-aged adolescents from PARI and maximize the benefits of PA.

This study investigated gender differences in the role of appraisals of safety in the relationship between exposure to violence and trauma-related symptoms among South African adolescents living in low socioeconomic settings. Limited research exists in developing contexts on the role of cognitive appraisals in mitigating outcome following exposure to violence. Given the prevalence of violence in South Africa and the vulnerability of youth, this type of research is valuable in identifying adolescents at risk of negative psychological outcome following exposure, and in informing intervention efforts. Adolescents (N = 498) completed an adapted version of the Harvard Trauma Questionnaire (Mollica et al., 1992) and the Safety Index (Ward, Flisher, Zissis, Muller, & Lombard, 2001). The results indicate a significant positive relationship between all violence subscales and trauma-related symptoms, whereas a significant negative relationship was found between sense of safety and trauma-related symptoms. Important gender differences were identified in the role of appraisals of safety, with more effects noted for women than men. For men, the obtained results only demonstrated a health-sustaining role. For women, the results indicated a health-sustaining role, an indirect effect, and a stress-reducing role. These findings stress the necessity of gender-specific interventions. Assessment of psychological trauma, particularly among female adolescents, needs to include measures of cognitive appraisals related to safety. Therapeutic techniques that may be particularly beneficial to adolescent girls are those focusing on promoting sense of safety and targeting dysfunctional threat appraisals.

To evaluate the feasibility of a novel "safety-valve" device for preventing catheter related urethral trauma during urethral catheterization (UC). To assess the opinions of clinicians on the performance of the safety-valve device. A validated prototype "safety-valve" device for preventing catheter balloon inflation related urethral injuries was prospectively piloted in male patients requiring UC in a tertiary referral teaching hospital (n = 100). The device allows fluid in the catheter system to decant through an activated safety threshold pressure valve if the catheter anchoring balloon is misplaced. Users evaluated the "safety-valve" with an anonymous questionnaire. The primary outcome measurement was prevention of anchoring balloon inflation in the urethra. Secondary outcome measurement was successful inflation of urinary catheter anchoring balloon in the bladder. Patient age was 76 ± 12 years and American Society of Anaesthesiologists grade was 3 ± 1.4. The "safety-valve" was utilized by 34 clinicians and activated in 7% (n = 7/100) patients during attempted UC, indicating that the catheter anchoring balloon was incorrectly positioned in the patient's urethra. In these 7 cases, the catheter was successfully manipulated into the urinary bladder and inflated. 31 of 34 (91%) clinicians completed the questionnaire. Ten percent (n = 3/31) of respondents had previously inflated a urinary catheter anchoring balloon in the urethra and 100% (n = 31) felt that a safety mechanism for preventing balloon inflation in the urethra should be compulsory for all UCs. The safety-valve device piloted in this clinical study offers an effective solution for preventing catheter balloon inflation related urethral injuries. Copyright © 2018 Elsevier Inc.

Impact of individual resilience and safety climate on safety performance and psychological stress of construction workers: A case study of the Ontario construction industry.

PubMed

Chen, Yuting; McCabe, Brenda; Hyatt, Douglas

2017-06-01

The construction industry has hit a plateau in terms of safety performance. Safety climate is regarded as a leading indicator of safety performance; however, relatively little safety climate research has been done in the Canadian construction industry. Safety climate may be geographically sensitive, thus it is necessary to examine how the construct of safety climate is defined and used to improve safety performance in different regions. On the other hand, more and more attention has been paid to job related stress in the construction industry. Previous research proposed that individual resilience may be associated with a better safety performance and may help employees manage stress. Unfortunately, few empirical research studies have examined this hypothesis. This paper aims to examine the role of safety climate and individual resilience in safety performance and job stress in the Canadian construction industry. The research was based on 837 surveys collected in Ontario between June 2015 and June 2016. Structural equation modeling (SEM) techniques were used to explore the impact of individual resilience and safety climate on physical safety outcomes and on psychological stress among construction workers. The results show that safety climate not only affected construction workers' safety performance but also indirectly affected their psychological stress. In addition, it was found that individual resilience had a direct negative impact on psychological stress but had no impact on physical safety outcomes. These findings highlight the roles of both organizational and individual factors in individual safety performance and in psychological well-being. Construction organizations need to not only monitor employees' safety performance, but also to assess their employees' psychological well-being. Promoting a positive safety climate together with developing training programs focusing on improving employees' psychological health - especially post-trauma psychological

Evidence-informed physical therapy management of performance-related musculoskeletal disorders in musicians

PubMed Central

Chan, Cliffton; Ackermann, Bronwen

2014-01-01

Playing a musical instrument at an elite level is a highly complex motor skill. The regular daily training loads resulting from practice, rehearsals and performances place great demands on the neuromusculoskeletal systems of the body. As a consequence, performance-related musculoskeletal disorders (PRMDs) are globally recognized as common phenomena amongst professional orchestral musicians. These disorders create a significant financial burden to individuals and orchestras as well as lead to serious consequences to the musicians’ performance and ultimately their career. Physical therapists are experts in treating musculoskeletal injuries and are ideally placed to apply their skills to manage PRMDs in this hyper-functioning population, but there is little available evidence to guide specific injury management approaches. An Australia-wide survey of professional orchestral musicians revealed that the musicians attributed excessively high or sudden increase in playing-load as major contributors to their PRMDs. Therefore, facilitating musicians to better manage these loads should be a cornerstone of physical therapy management. The Sound Practice orchestral musicians work health and safety project used formative and process evaluation approaches to develop evidence-informed and clinically applicable physical therapy interventions, ultimately resulting in favorable outcomes. After these methodologies were employed, the intervention studies were conducted with a national cohort of professional musicians including: health education, onsite injury management, cross-training exercise regimes, performance postural analysis, and music performance biomechanics feedback. The outcomes of all these interventions will be discussed alongside a focussed review on the existing literature of these management strategies. Finally, a framework for best-practice physical therapy management of PRMDs in musicians will be provided. PMID:25071671

Body-related self-conscious emotions relate to physical activity motivation and behavior in men.

The aim of this study was to examine the associations between the body-related self-conscious emotions of shame, guilt, and pride and physical activity motivation and behavior among adult males. Specifically, motivation regulations (external, introjected, indentified, intrinsic) were examined as possible mediators between each of the body-related self-conscious emotions and physical activity behavior. A cross-sectional study was conducted with adult men (N = 152; Mage = 23.72, SD = 10.92 years). Participants completed a questionnaire assessing body-related shame, guilt, authentic pride, hubristic pride, motivational regulations, and leisure-time physical activity. In separate multiple mediation models, body-related shame was positively associated with external and introjected regulations and negatively correlated with intrinsic regulation. Guilt was positively linked to external, introjected, and identified regulations. Authentic pride was negatively related to external regulation and positively correlated with both identified and intrinsic regulations and directly associated with physical activity behavior. Hubristic pride was positively associated with intrinsic regulation. Overall, there were both direct and indirect effects via motivation regulations between body-related self-conscious emotions and physical activity (R(2) shame = .15, guilt = .16, authentic pride = .18, hubristic pride = .16). These findings highlight the importance of targeting and understanding self-conscious emotions contextualized to the body and links to motivation and positive health behavior among men. © The Author(s) 2014.

Transformational leadership and safety performance among nurses: the mediating role of knowledge-related job characteristics.

2014-03-01

To report the impact of transformational leadership on two dimensions of nurses' safety performance (i.e. safety compliance and safety participation) and to study the mediating role of knowledge-related job characteristics in this relationship. Safety performance refers to the behaviours that employees exhibit to adhere to safety guidelines and to promote health and safety at their workplace. Nurses' safety performance is a major challenge for healthcare settings, urging the need to identify the key determinants and psychological mechanisms that influence it. A cross-sectional survey study. The study was carried out in September 2010 in a large Belgian hospital. We used self-administered questionnaires; 152 nurses participated. The hypotheses were tested using hierarchical regression analyses. In line with our first hypothesis, the results show that transformational leadership exerted a significant positive impact on both dimensions of nurses' safety performance. This positive relation was mediated by knowledge-related job characteristics, supporting our second hypothesis. Head nurses' transformational leadership can enhance nurses' compliance with and participation in safety. Furthermore, transformational head nurses are able to influence the perception that their nurses have about the kind and amount of knowledge in their job, which can also lead to increases in both dimensions of nurses' safety performance. This study therefore demonstrates the key impact that transformational head nurses have, both directly and indirectly, on the safety performance of their nurses. © 2013 John Wiley & Sons Ltd.

To report an exploration of the multidimensionality of safety in cardiac rehabilitation programmes as perceived by women who were enrolled in the Women's Cardiovascular Health Initiative in Toronto, Canada. Cardiovascular disease is the leading cause of death among women. Although cardiac rehabilitation is clinically effective, significantly fewer women than men participate in available programmes. The literature identifies factors affecting women's cardiac rehabilitation participation, and provides possible explanations for this gender disparity. Although safety is mentioned among the barriers to women's cardiac rehabilitation participation, the extent to which safety contributes to programme participation, completion, and maintenance remains under-explored in the cardiac rehabilitation literature. We conducted an exploratory qualitative study to examine the role safety and place play for women engaged in cardiac prevention and rehabilitation at the Women's Cardiovascular Health Initiative. Methods.  From 2005-2006, 14 participants engaged in semi-structured, qualitative interviews lasting 30-90 minutes. Discussions addressed women's experiences at the Women's Cardiovascular Health Initiative. Interview transcripts were analysed using thematic analysis. Three themes were developed: 'Safety', which was sub-categorized according to physical, social, and symbolic interpretations of safety, 'searching for a sense of place', and 'confidence and empowerment'. Feeling physically, socially, and symbolically safe in one's cardiac rehabilitation environment may contribute to programme adherence and exercise maintenance for women. Focusing on comprehensive notions of safety in future cardiac rehabilitation research could offer insight into why many women do not maintain an exercise regimen in currently structured cardiac rehabilitation and community programmes. © 2012 Blackwell Publishing Ltd.

Using minority stress theory, the authors investigated risk behaviors of transgender women (trans women) in Lebanon. Using semistructured interviews, the authors explored six areas: relationships with family and friends; openness about gender and sexuality; experiences with stigma; sexual behavior; attitudes and behaviors regarding HIV testing; and perceived HIV-related norms among transgender peers. Participants voiced the importance of different forms of safety: social/emotional, physical, sexual, and financial. Strategies for obtaining safety were negotiated differently depending on social, behavioral, and structural factors in the environment. In this article, we provide study findings from the perspectives of trans women, their exposure to stigma, and the necessary navigation of environments characterized by transphobia. PMID:24588138

To examine the content and trends of safety-related consumer information in magazine vehicle advertisements, as a case study within the worldwide marketing of vehicles. Content analysis of popular current affairs magazines in New Zealand for the 5-year period 2001-2005 was undertaken (n = 514 advertisements), supplemented with vehicle data from official websites. Safety information in advertisements for light passenger vehicles was relatively uncommon with only 27% mentioning one or more of nine key safety features examined (average: 1.7 out of nine features in this 27%). Also included were potentially hazardous features of: speed imagery (in 29% of advertisements), power references (14%), and acceleration data (4%). The speed and power aspects became relatively more common over the 5-year period (p < 0.05 for trend). To enhance informed consumer choice and improve injury prevention, governments should consider regulating the content of vehicle advertisements and vehicle marketing - as already occurs with many other consumer products.

2006-02-01

We sought to determine the relative effectiveness of different methods of worker safety and health training aimed at improving safety knowledge and performance and reducing negative outcomes (accidents, illnesses, and injuries). Ninety-five quasi-experimental studies (n=20991) were included in the analysis. Three types of intervention methods were distinguished on the basis of learners' participation in the training process: least engaging (lecture, pamphlets, videos), moderately engaging (programmed instruction, feedback interventions), and most engaging (training in behavioral modeling, hands-on training). As training methods became more engaging (i.e., requiring trainees' active participation), workers demonstrated greater knowledge acquisition, and reductions were seen in accidents, illnesses, and injuries. All methods of training produced meaningful behavioral performance improvements. Training involving behavioral modeling, a substantial amount of practice, and dialogue is generally more effective than other methods of safety and health training. The present findings challenge the current emphasis on more passive computer-based and distance training methods within the public health workforce.

This study was designed to explore the effects of a health-related physical fitness physical education model on students' physical activity, perceived competence, and enjoyment. 61 students (25 boys, 36 girls; M age = 12.6 yr., SD = 0.6) were assigned to two groups (health-related physical fitness physical education group, and traditional physical education group), and participated in one 50-min. weekly basketball class for 6 wk. Students' in-class physical activity was assessed using NL-1000 pedometers. The physical subscale of the Perceived Competence Scale for Children was employed to assess perceived competence, and children's enjoyment was measured using the Sport Enjoyment Scale. The findings suggest that students in the intervention group increased their perceived competence, enjoyment, and physical activity over a 6-wk. intervention, while the comparison group simply increased physical activity over time. Children in the intervention group had significantly greater enjoyment.

Chirality: a relational geometric-physical property.

PubMed

Gerlach, Hans

2013-11-01

The definition of the term chirality by Lord Kelvin in 1893 and 1904 is analyzed by taking crystallography at that time into account. This shows clearly that chirality is a relational geometric-physical property, i.e., two relations between isometric objects are possible: homochiral or heterochiral. In scientific articles the relational term chirality is often mistaken for the two valued measure for the individual (absolute) sense of chirality, an arbitrary attributive term. © 2013 Wiley Periodicals, Inc.

The moderating role of safety-specific trust on the relation between safety-specific leadership and safety citizenship behaviors.

Conchie, Stacey M; Donald, Ian J

2009-04-01

The authors examined whether safety-specific trust moderates or mediates the relationship between safety-specific transformational leadership and subordinates' safety citizenship behavior. Data from 139 subordinate-supervisor dyads were collected from the United Kingdom construction industry and analyzed using hierarchical regression models. Results showed that safety-specific trust moderated rather than mediated the effects of safety-specific transformational leaders on subordinates' behavior. Specifically, in conditions of high and moderate safety-specific trust, leaders had a significant effect on subordinates' safety citizenship behavior. However, in conditions of low safety-specific trust, leaders did not significantly influence subordinates' safety citizenship behavior. The implications of these findings for general safety theory and practice are discussed.

Exploring factors related to physical activity in cervical dystonia.

People with disabilities have reported worse health status than people without disabilities and receiving fewer preventive health services such as counseling around exercise habits. This is noteworthy considering the negative consequences associated with physical inactivity. No research has been conducted on physical activity in cervical dystonia (CD), despite its possible major impact on self-perceived health and disability. Considering the favorable consequences associated with physical activity it is important to know how to promote physical activity behavior in CD. Knowledge of variables important for such behavior in CD is therefore crucial. The aim of this study was to explore factors related to physical activity in individuals with cervical dystonia. Subjects included in this cross-sectional study were individuals diagnosed with CD and enrolled at neurology clinics (n = 369). Data was collected using one surface mailed self-reported questionnaire. Physical activity was the primary outcome variable, measured with the Physical Activity Disability Survey. Secondary outcome variables were: impact of dystonia measured with the Cervical Dystonia Impact Scale; fatigue measured with the Fatigue Severity Scale; confidence when carrying out physical activity measured with the Exercise Self-Efficacy Scale; confidence in performing daily activities without falling measured with the Falls Efficacy Scale; enjoyment of activity measured with Enjoyment of Physical Activity Scale, and social influences on physical activity measured with Social Influences on Physical Activity in addition to demographic characteristics such as age, education level and employment status. The questionnaire was completed by 173 individuals (47% response rate). The multivariate association between related variables and physical activity showed that employment, self-efficacy for physical activity, education level and consequences for daily activities explained 51% of the variance in physical

Applying GPS to enhance understanding of transport-related physical activity.

Duncan, Mitch J; Badland, Hannah M; Mummery, W Kerry

2009-09-01

The purpose of the paper is to review the utility of the global positioning system (GPS) in the study of health-related physical activity. The paper draws from existing literature to outline the current work performed using GPS to examine transport-related physical activity, with a focus on the relative utility of the approach when combined with geographic information system (GIS) and other data sources including accelerometers. The paper argues that GPS, especially when used in combination with GIS and accelerometery, offers great promise in objectively measuring and studying the relationship of numerous environmental attributes to human behaviour in terms of physical activity and transport-related activity. Limitations to the use of GPS for the purpose of monitoring health-related physical activity are presented, and recommendations for future avenues of research are discussed.

2016-08-01

Second victim experiences can affect the wellbeing of health care providers and compromise patient safety. Many factors associated with improved coping after patient safety event involvement are also components of a strong patient safety culture, so that supportive patient safety cultures may reduce second victim-related trauma. A cross-sectional survey study was conducted to assess the influence of patient safety culture on second victim-related distress. The Agency for Healthcare Research and Quality (AHRQ) Hospital Survey on Patient Safety Culture (HSOPSC) and the Second Victim Experience and Support Tool (SVEST), which was developed to assess organizational support and personal and professional distress after involvement in a patient safety event, were administered to nurses involved in direct patient care. Of 358 nurses at a specialized pediatric hospital, 169 (47.2%) completed both surveys. Hierarchical linear regres sion demonstrated that the patient safety culture survey dimension nonpunitive response to error was significantly associated with reductions in the second victim survey dimensions psychological, physical, and professional distress (p < 0.001). As a mediator, organizational support fully explained the nonpunitive response to error-physical distress and nonpunitive response to error-professional distress relationships and partially explained the nonpunitive response to error-psychological distress relationship. The results suggest that punitive safety cultures may contribute to self-reported perceptions of second victim-related psychological, physical, and professional distress, which could reflect a lack of organizational support. Reducing punitive response to error and encouraging supportive coworker, supervisor, and institutional interactions may be useful strategies to manage the severity of second victim experiences.

In this study, we assess how the Scania Green Score (SGS5), and the five distinct perceived neighbourhood green dimensions within this area-aggregated index (1km 2 squares), is associated with self-reported physical activity and general health, and if perceived safety and social coherence has a moderating effect. Two independent surveys, both conducted in Scania, Sweden, was used for data on SGS5 and health outcomes (N=28 198 and N=23 693), respectively. SGS5 was more clearly associated with physical activity (OR 1.06; 95% CI 1.02-1.10) than with general health (OR 1.02; 95% CI 1.00-1.04). This association was moderated by safety (p for interaction <0.001); SGS5 was positively associated with physical activity only among individuals who perceived high safety in their neighbourhood (OR 1.07; 95% CI 1.02-1.11). No moderating effect was seen for social coherence. Among specific dimensions, cultural history was positively associated with both physical activity and general health. Our results suggest that perception of safety is a prerequisite for the positive effects of neighbourhood green qualities. Copyright © 2017 Elsevier Ltd. All rights reserved.

The aim of this study was to examine different socio-demographic, health and safety-related factors, and psychoactive substance use among fatally injured drivers in road traffic accidents in Finland during 2006-2008. An accident information register maintained by the Traffic Safety Committee of Insurance Companies (VALT) of the Finnish Motor Insurers' Centre was used as basic data, and the basic data were complemented with further toxicological analytical information retrieved from autopsy reports from the Department of Forensic Medicine, Helsinki University. The data included all the drivers (n=556) who were driving a motor vehicle and who died in a road traffic accident in Finland during 2006-2008. Of all the 556 fatally injured drivers 43% (n=238) had psychoactive substance findings. 51% (n=121) of substance positive drivers had a finding for alcohol only, the rest had a finding for one or more illicit/medicinal drugs impairing driving ability, and possibly also alcohol. Fatally injured drivers with alcohol findings were significantly younger (mean age 34 years) than sober drivers (mean age 44 years) or drivers with findings for drugs (mean age 45 years). Socio-demographic background did not differ substantially among drunken/drugged and sober drivers, although drivers with alcohol findings had a slightly lower education and socioeconomic position. Previous substance abuse problems were highly prevalent among drivers with substance findings and mental or both mental and physical health problems were more common among drivers with drug findings. The non-use of safety equipment and driving at a high speed were more common among fatally injured drivers with substance findings. Substance abuse and mental health problems, as well as reckless driving behavior were more pronounced among fatally injured drivers with substance findings when compared to sober drivers. Thus, prevention and early intervention concerning substance abuse, mental health problems and DUI are

Relational approach in managing construction project safety: a social capital perspective.

PubMed

Koh, Tas Yong; Rowlinson, Steve

2012-09-01

Existing initiatives in the management of construction project safety are largely based on normative compliance and error prevention, a risk management approach. Although advantageous, these approaches are not wholly successful in further lowering accident rates. A major limitation lies with the approaches' lack of emphasis on the social and team processes inherent in construction project settings. We advance the enquiry by invoking the concept of social capital and project organisational processes, and their impacts on project safety performance. Because social capital is a primordial concept and affects project participants' interactions, its impact on project safety performance is hypothesised to be indirect, i.e. the impact of social capital on safety performance is mediated by organisational processes in adaptation and cooperation. A questionnaire survey was conducted within Hong Kong construction industry to test the hypotheses. 376 usable responses were received and used for analyses. The results reveal that, while the structural dimension is not significant, the mediational thesis is generally supported with the cognitive and relational dimensions affecting project participants' adaptation and cooperation, and the latter two processes affect safety performance. However, the cognitive dimension also directly affects safety performance. The implications of these results for project safety management are discussed. Copyright © 2011 Elsevier Ltd.

The aim of this study was to examine the understanding of snowboard-related concussion and to measure the recognition of possible concussion occurrence after an intervention of snowboard-related concussion safety education in snowboarding. Incidence cohort design. 2008-2009 season Gangwon-do Ski resorts, South Korea. A total of 208 university students (female-72; male-136; age-18 to 32) who registered for a snowboarding class and received credit participated in this project. Snowboard-related concussion safety education class was administered for 30 minutes before the snowboard class began. The knowledge of snowboard-related concussion before and after the safety education was evaluated. Concussion data were collected via a self-report case form at the last day of snowboarding class. The incidence of possible concussion and factors associated with concussions were analyzed by χ2 test. The mean score of snowboard-related concussion knowledge improved from fifteen points to eighteen points out of 20 total points possible. Overall the incidence of concussion was 10 per 100 snowboarder-exposures. χ2 tests showed concussion rates to be significantly different in female snowboarders (P=0.00) and in helmet users (P=0.02). The incidence of possible concussion is high among snowboarding class participants. Emphasis should be given for instituting pre-participation balance training, especially for females to reduce falling in snowboarding. To verify the effects of pre-participation balance training and falling results in a concussion, more research is needed in the future.

Sports and physical activity are transforming, and being transformed by, the societies in which they are practised. From the perspectives of both competitive and non-competitive sports, the complexity of their integration into today's society has led to neither sports federations nor governments being able to manage the safety problem alone. In other words, these agencies, whilst promoting sport and physical activity, deliver policy and practices in an uncoordinated way that largely ignores the need for a concurrent overall policy for sports safety. This article reviews and analyses the possibility of developing an overall sports safety policy from a global viewpoint. Firstly, we describe the role of sports in today's societies and the context within which much sport is delivered. We then discuss global issues related to injury prevention and safety in sports, with practical relevance to this important sector, including an analysis of critical policy issues necessary for the future development of the area and significant safety gains for all. We argue that there is a need to establish the sports injury problem as a critical component of general global health policy agendas, and to introduce sports safety as a mandatory component of all sustainable sports organizations. We conclude that the establishment of an explicit intersection between science and policy making is necessary for the future development of sports and the necessary safety gains required for all participants around the world. The Safe Sports International safety promotion programme is outlined as an example of an international organization active within this arena.

To determine the proportion of unintentional and undetermined firearm related deaths preventable by three safety devices: personalization devices, loaded chamber indicators (LCIs), and magazine safeties. A personalized gun will operate only for an authorized user, a LCI indicates when the gun contains ammunition, and a magazine safety prevents the gun from firing when the ammunition magazine is removed. Information about all unintentional and undetermined firearm deaths from 1991-98 was obtained from the Office of the Chief Medical Examiner for Maryland, and from the Wisconsin Firearm Injury Reporting System for Milwaukee. Data regarding the victim, shooter, weapon, and circumstances were abstracted. Coding rules to classify each death as preventable, possibly preventable, or not preventable by each of the three safety devices were also applied. There were a total of 117 firearm related deaths in our sample, 95 (81%) involving handguns. Forty three deaths (37%) were classified as preventable by a personalized gun, 23 (20%) by a LCI, and five (4%) by a magazine safety. Overall, 52 deaths (44%) were preventable by at least one safety device. Deaths involving children 0-17 (relative risk (RR) 3.3, 95% confidence interval (CI) 2.1 to 5.1) and handguns (RR 8.1, 95% CI 1.2 to 53.5) were more likely to be preventable. Projecting the findings to the entire United States, an estimated 442 deaths might have been prevented in 2000 had all guns been equipped with these safety devices. Incorporating safety devices into firearms is an important injury intervention, with the potential to save hundreds of lives each year.

A vicious circle of decreased physical fitness, early fatigue, and low physical activity levels (PAL) is thought to affect children with cerebral palsy (CP). However, the relationship of changes in physical fitness to changes in PAL and fatigue is unclear. The objective of this study was to investigate the associations among changes in physical fitness, walking-related PAL, and fatigue in children with CP. This study was a secondary analysis of a randomized controlled trial with measurements at baseline, 6 months (after the intervention period), and 12 months. Twenty-four children with bilateral spastic CP and 22 with unilateral spastic CP, aged 7 to 13 years, all walking, participated in this study. Physical fitness was measured by aerobic capacity, anaerobic threshold, anaerobic capacity, and isometric and functional muscle strength. Walking-related PAL was measured using an ankle-worn activity monitor for 1 week. Fatigue was determined with the Pediatric Quality of Life (PedsQL) Multidimensional Fatigue Scale. Longitudinal associations were analyzed by random coefficient regression analysis. In children with bilateral CP, all fitness parameters showed a positive, significant association with walking-related PAL, whereas no associations between physical fitness and walking-related PAL were seen in children with unilateral CP. No clinically relevant association between physical fitness and fatigue was found. Although random coefficient regression analysis can be used to investigate longitudinal associations between parameters, a causal relationship cannot be determined. The actual direction of the association between physical fitness and walking-related PAL, therefore, remains inconclusive. Children with bilateral spastic CP might benefit from improved physical fitness to increase their PAL or vice versa, although this is not the case in children with unilateral CP. There appears to be no relationship between physical fitness and self-reported fatigue in children

There is a lack of empirical knowledge about nurses' perceptions of their workplace characteristics and conditions, such as level of autonomy and decision authority, work climate, teamwork, skill exploitation and learning opportunities, and their work motivation in relation to practice outputs such as patient safety. Such knowledge is needed particularly in countries, such as Estonia, where hospital systems for preventing errors and improving patient safety are in the early stages of development. This article reports the findings from a cross-sectional survey of hospital nurses in Estonia that was aimed at determining their perceptions of workplace characteristics, working conditions, work motivation and patient safety, and at exploring the relationship between these. Results suggest that perceptions of personal control over their work can affect nurses' motivation, and that perceptions of work satisfaction might be relevant to patient safety improvement work.

Sexual violence and pregnancy-related physical symptoms

PubMed Central

2012-01-01

Background Few studies have investigated the impact of sexual violence on health during pregnancy. We examined the association between sexual violence and the reporting of physical symptoms during pregnancy. Methods A population-based national cohort study conducted by The Norwegian Mother and Child Cohort study (MoBa) collected data from pregnant women through postal questionnaires at 17 and 32 weeks gestation. Three levels of sexual violence were measured: 1) mild (pressured into sexual relations), 2) moderate (forced with violence into sexual relation) and 3) severe (rape). Differences between women reporting and not reporting sexual violence were assessed using Pearson’s X2 test and multiple logistic regression analyses. Results Of 78 660 women, 12.0% (9 444) reported mild, 2.8% (2 219) moderate and 3.6% (2 805) severe sexual violence. Sexual violence was significantly associated with increased reporting of pregnancy-related physical symptoms, both measured in number of symptoms and duration/degree of suffering. Compared to women not reporting sexual violence, the probability of suffering from ≥8 pregnancy-related symptoms estimated by Adjusted Odds Ratio (AOR) was 1.49 (1.41–1.58) for mild sexual violence, 1.66(1.50–1.84) for moderate and 1.78 (1.62–1.95) for severe. Severe sexual violence both previously and recently had the strongest association with suffering from ≥8 pregnancy-related symptoms, AOR 6.70 (2.34–19.14). Conclusion A history of sexual violence is associated with increased reporting of pregnancy-related physical symptoms. Clinicians should consider the possible role of a history of sexual violence when treating women who suffer extensively from pregnancy-related symptoms. PMID:22883753

This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices. Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence. In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant. This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices.

Microbiological Safety of Animal Wastes Processed by Physical Heat Treatment: An Alternative To Eliminate Human Pathogens in Biological Soil Amendments as Recommended by the Food Safety Modernization Act.

PubMed

Chen, Zhao; Jiang, Xiuping

2017-03-01

Animal wastes have high nutritional value as biological soil amendments of animal origin for plant cultivation in sustainable agriculture; however, they can be sources of some human pathogens. Although composting is an effective way to reduce pathogen levels in animal wastes, pathogens may still survive under certain conditions and persist in the composted products, which potentially could lead to fresh produce contamination. According to the U.S. Food and Drug Administration Food Safety Modernization Act, alternative treatments are recommended for reducing or eliminating human pathogens in raw animal manure. Physical heat treatments can be considered an effective method to inactivate pathogens in animal wastes. However, microbial inactivation in animal wastes can be affected by many factors, such as composition of animal wastes, type and physiological stage of the tested microorganism, and heat source. Following some current processing guidelines for physical heat treatments may not be adequate for completely eliminating pathogens from animal wastes. Therefore, this article primarily reviews the microbiological safety and economic value of physically heat-treated animal wastes as biological soil amendments.

All-terrain vehicle (ATV) usage has grown tremendously over the years, reaching 9.5 million vehicles in use in 2007. Accompanying this growth has been a concomitant increase in rider morbidity (including traumatic brain and spine injuries) and death, especially in children. The purpose of this study was to define and measure, through field testing, those physical attributes intrinsic to riders, such as height, weight, and wingspan, which may have implications for ATV riders' safety. Three field tests (J-hook, brake, and bump) were developed and performed to allow direct measurement of the lateral, longitudinal, and vertical dynamics in 5 riders of varying heights, weights, and wingspans. Two ATVs, a utility and a sport model, were tested for further comparisons. Data were acquired using a comprehensive data acquisition system attached to the ATVs. Assignment of individual rider/ATV test safety ratings and a rider/ATV Total Safety Rating were made from the results of these field tests. The J-hook test results demonstrated that larger rider wingspans positively influence ATV rider safety and mitigate against lateral instability. From the brake test it was determined that a 10-in (25.4-cm) longitudinal displacement, such as that experienced during a sharp deceleration, for a rider of any height or weight, breached the level of defined safety. As rider weight increased, displacement decreased. The bump test provided evidence that increased rider weight also mitigates against vertical displacement. Individuals with light weights and small wingspans, such as those in the pediatric population, are under considerable risk of injury when operating an ATV due to lateral, longitudinal, and vertical operational instability.

2015-03-17

Over the past few decades the increased level of public awareness concerning healthcare, physical activities, safety and environmental sensing has created an emerging need for smart sensor technologies and monitoring devices able to sense, classify, and provide feedbacks to users' health status and physical activities, as well as to evaluate environmental and safety conditions in a pervasive, accurate and reliable fashion. Monitoring and precisely quantifying users' physical activity with inertial measurement unit-based devices, for instance, has also proven to be important in health management of patients affected by chronic diseases, e.g., Parkinson's disease, many of which are becoming highly prevalent in Italy and in the Western world. This review paper will focus on MEMS sensor technologies developed in Italy in the last three years describing research achievements for healthcare and physical activity, safety and environmental sensing, in addition to smart systems integration. Innovative and smart integrated solutions for sensing devices, pursued and implemented in Italian research centres, will be highlighted, together with specific applications of such technologies. Finally, the paper will depict the future perspective of sensor technologies and corresponding exploitation opportunities, again with a specific focus on Italy.

Dukes, Richard L; Stein, Judith A; Zane, Jazmin I

2010-12-01

Using structural equation modeling, concurrent associations were assessed among physical bullying, relational bullying, physical victimization, relational victimization, injury and weapon carrying using data from the population of 1300 adolescent girls and 1362 adolescent boys in grades 7-12 in a Colorado school district. For both genders, being a relational bully was a significantly stronger predictor of weapon carrying than being a physical bully, and both bullying types were significant predictors of more weapon carrying. For both genders, being a victim of physical bullying, a victim of relational bullying, or being a relational bully significantly predicted more injury. In latent means comparisons, adolescent girls reported more relational victimization and adolescent boys reported more physical bullying and victimization, more weapon carrying, and more injury. The relative strength of relational bullying on weapon carrying, and the health-related consequences of bullying on interpersonal violence and injury support concerted efforts in schools to mitigate these behaviors. Attention to differences related to age and gender also is indicated in the design of bullying mitigation programs. Copyright © 2010 Society for the Study of School Psychology.

Wu, Kun-Feng; Aguero-Valverde, Jonathan; Jovanis, Paul P

2014-11-01

There has been considerable research conducted over the last 40 years using traffic safety-related events to support road safety analyses. Dating back to traffic conflict studies from the 1960s these observational studies of driver behavior have been criticized due to: poor quality data; lack of available and useful exposure measures linked to the observations; the incomparability of self-reported safety-related events; and, the difficulty in assessing culpability for safety-related events. This study seeks to explore the relationships between driver characteristics and traffic safety-related events, and between traffic safety-related events and crash involvement while mitigating some of those limitations. The Virginia Tech Transportation Institute 100-Car Naturalistic Driving Study dataset, in which the participants' vehicles were instrumented with various cameras and sensors during the study period, was used for this study. The study data set includes 90 drivers observed for 12-13 months driving. This study focuses on single vehicle run-off-road safety-related events only, including 14 crashes and 182 safety-related events (30 near crashes, and 152 crash-relevant incidents). Among the findings are: (1) drivers under age 25 are significantly more likely to be involved in safety-related events and crashes; and (2) significantly positive correlations exist between crashes, near crashes, and crash-relevant incidents. Although there is still much to learn about the factors affecting the positive correlation between safety-related events and crashes, a Bayesian multivariate Poisson log-normal model is shown to be useful to quantify the associations between safety-related events and crash risk while controlling for driver characteristics.

Hertz's special relativity and physical reality.

NASA Astrophysics Data System (ADS)

Mocanu, C. I.

Maxwell-Hertz electrodynamics (MHE), valid for nonuniform motions as they occur in physical reality and which holds for the noninertial reference frame of our laboratory at small velocities only, is extended to relativistic velocities. The new theory, called Hertz's relativistic electrodynamics (HRE), is completely independent and built-up in a completely different way than Einstein's special relativity (ESR). HRE, a coordinate-free formulation, does not need postulates, but confirms the constancy principle of the speed of light in a vacuum. All experiments of first and second order in v2/c2 are correctly interpreted. To this theory a Hertzian kinematics and dynamics are associated. HRE with its corresponding mechanics form Hertz's special relativity (HSR) as a theory complementary to ESR. According to the principle of complementarity and neglecting gravitational effects, extended special relativity (ExSR) is a double-faced theory which becomes either ESR when the motion is inertial or HSR when the motion is noninertial. The complementarity of both theories assumes that the two descriptions cannot be employed for the same motion, being mutually exclusive. Consequently, to every statement of ExSR, a complementary statement of the other ExSR corresponds. The completeness of ESR with HSR ensures an extended view over relativity in our physical world.

Objectives This paper sought to assess organizational safety practices at three different levels of hierarchical workplace structure and to examine their association with injury outcomes among construction apprentices. Methods Using a cross-sectional sample of 1,775 construction apprentices, three measures of organizational safety practice were assessed: contractor-, steward-, and coworker-safety practice. Each safety practice measure was assessed using three similar questions (i.e., on-the-job safety commitment, following required or recommended safe work practices, and correcting unsafe work practices); the summed average of the responses ranged from 1 to 4, with a higher score indicating poorer safety practice. Outcome variables included the prevalence of four types of musculoskeletal pain (i.e., neck, shoulder, hand, and back pain) and injury-related absence. Results In adjusted analyses, contractor-safety practice was associated with both hand pain (OR: 1.27, 95 % CI: 1.04, 1.54) and back pain (OR: 1.40, 95 % CI: 1.17, 1.68); coworker-safety practice was related to back pain (OR: 1.42, 95 % CI: 1.18, 1.71) and injury-related absence (OR: 1.36, 95 % CI: 1.11, 1.67). In an analysis that included all three safety practice measures simultaneously, the association between coworker-safety practice and injury-related absence remained significant (OR: 1.68, 95 % CI: 1.20, 2.37), whereas all other associations became non-significant. Conclusions This study suggests that organizational safety practice, particularly coworker-safety practice, is associated with injury outcomes among construction apprentices. PMID:23748366

Individuals with disabilities face increasing health and employment disparities, including increased risk of morbidity and mortality and decreased earnings, occupational roles, and greater risk of injury at work. Thus, there is a need to improve workplace safety and health promotion efforts for people with disability. The purpose of this study was to obtain stakeholder feedback about an online program, Be Active, Work Safe, which was developed to increase the physical activity and workplace safety practices of individuals with disability. Eight stakeholders (content experts and individuals with disability) evaluated the 8-week online program and provided feedback on accessibility, usability, and content using quantitative and qualitative approaches. Stakeholders suggested changes to the organization, layout and accessibility, and content. This included making a stronger connection between the physical activity and workplace safety components of the program, broadening content to apply to individuals in different vocational fields, and reducing the number of participant assessments. Engaging stakeholders in the development of health promotion programs is critical to ensure the unique issues of the population are addressed and facilitate engagement in the program. Feedback provided by stakeholders improved the program and provided insight on barriers for adoption of the program. Copyright © 2017 Elsevier Ltd. All rights reserved.

Underwriters Laboratories has conducted a study to identify and develop safety requirements for photovoltaic module and panel designs and configurations for residential, intermediate, and large scale applications. Concepts for safety systems, where each system is a collection of subsystems which together address the total anticipated hazard situation, are described. Descriptions of hardware, and system usefulness and viability are included. This discussion of safety systems recognizes that there is little history on which to base the expected safety related performance of a photovoltaic system. A comparison of these systems, as against the provisions of the 1984 National Electrical Code covering photovoltaicmore » systems is made. A discussion of the UL investigation of the photovoltaic module evaluated to the provisions of the Proposed UL Standard for Flat-Plate Photovoltaic Modules and Panels is included. Grounding systems, their basis and nature, and the advantages and disadvantages of each are described. The meaning of frame grounding, circuit grounding, and the type of circuit ground are covered. The development of the Standard for Flat-Plate Photovoltaic Modules and Panels has continued, and with both industry comment and a product submittal and listing, the Standard has been refined to a viable document allowing an objective safety review of photovoltaic modules and panels. How this document, and other UL documents would cover investigations of certain other photovoltaic system components is described.« less

Safety of Cancer Therapies: At What Cost?

PubMed

Fitzner, Karen; Oteng-Mensah, Frederick; Donley, Patrick; Heckinger, Elizabeth A F

2017-08-01

The cost of cancer drugs has increased concurrently with drug safety resulting in both increased survivorship and increased out-of-pocket costs and co-payments for patients. This article evaluates the interplay between patient safety and cancer drug costs to determine how cancer drug costs affect patient safety and well-being. A literature review was performed that identified the main drivers of drug safety costs: drug-drug interactions, adverse drug events, medication errors, and nonadherence. Three main types of costs were identified: out-of-pocket spending, drug cost growth, and safety-related costs. Insured patients receiving chemotherapy pay an average of $10,000/month on out-of-pocket expenses. Annual drug cost growth has been as much as 21% in recent years. Over a span of 13 years, 1999-2013, insurance premiums and out-of-pocket payments have increased by 182% and 200%, respectively. Safety-related concerns include the high cost of developing a new drug, estimated at $5 billion. The cost of development is reflected in the cost of the 12 new cancer drugs that received Food and Drug Administration approval in 2012; 11 were priced at 6 figures. Although advances in pharmaceutical technology and research have yielded effective cancer therapies that reduce physical or treatment-related toxicity, patients have had to face worsening financial uncertainty both during and after treatment. Actions are needed to achieve financial safety, as well as therapeutic and clinical safety, for cancer patients.

The physical and social environments at schools are related to students' moderate-to-vigorous physical activity (MVPA) levels. The purpose of this study was to explore the interactive effects of the school physical environment and school social capital on the MVPA of students while at school. Data from 18,875 grade 6-10 students from 331 schools who participated in the 2009/10 Canadian Health Behaviour in School-Aged Children survey were analyzed using multi-level regression. Students answered questions on the amount of time they spend in MVPA at school and on their school's social capital. Administrator reports were used to create a physical activity related physical environment score. The school physical environment score was positively associated with student MVPA at school (β = 0.040, p < .005). The association between the school social capital and MVPA was also positive (β = 0.074, p < .001). The difference in physical environments equated to about 20 minutes/week of MVPA for students attending schools with the lowest number of physical environment features and about 40 minutes/week for students attending schools with the lowest school social capital scores by comparison to students attending schools with the highest scores. The findings suggest that school social capital may be a more important factor in increasing students MVPA than the school physical environment. The results of this study may help inform interventions aimed at increasing student physical activity levels.

Food safety assessment and communication have a strong importance in reducing human health risks related to food consumption. The research carried out within the ECsafeSEAFOOD project aims to assess seafood safety issues, mainly related to non-regulated priority environmental contaminants, and to evaluate their impact on public health. In order to make the research results accessible and exploitable, and to respond to actual stakeholders' demands, a consultation with international stakeholders was performed by means of a survey. The focus was on policy and decision makers, food producers and processors, and agencies (i.e. EU and National or Regional agencies related to Foodmore » Safety or Public Health) and consumer organisations. The survey considered questions related to: seafood safety assessment and mitigation strategies, availability of data, such as the level of information on different contaminants, and communication among different stakeholder groups. Furthermore, stakeholders were asked to give their opinion on how they believe consumers perceive risks associated with environmental contaminants. The survey was distributed to 531 key stakeholders and 91 responses were received from stakeholders from 30 EU and non-EU countries. The main results show that communication between different groups of stakeholders needs to be improved and that there is a deficit of information and data in the field of seafood safety. This pertains mainly to the transfer of contaminants between the environment and seafood, and to the diversity of environmental contaminants such as plastic additives, algal toxins and hormones. On-line tools were perceived to be the most useful communication channel. - Highlights: • We consulted stakeholders to identify their needs about seafood safety. • An on-line survey was prepared and sent to gather stakeholders' opinions. • Communication among stakeholders needs to be improved. • There is a deficit of information and data in the

Better physical functioning in the elderly may be associated with higher physical activity levels. Since older adults spend a substantial part of the day in their residential neighborhood, the neighborhood physical environment may moderate associations between functioning and older adults' physical activity. The present study investigated the moderating role of the objective and perceived physical environment on associations between Belgian older adults' physical functioning and transport walking, recreational walking, and moderate-to-vigorous physical activity. Data from 438 older adults were included. Objective physical functioning was assessed using the Short Physical Performance Battery. Potential moderators included objective neighborhood walkability and perceptions of land use mix diversity, access to recreational facilities, access to services, street connectivity, physical barriers for walking, aesthetics, crime-related safety, traffic speeding-related safety, and walking infrastructure. Transport and recreational walking were self-reported, moderate-to-vigorous physical activity was assessed through accelerometers. Multi-level regression analyses were conducted using MLwiN to examine two-way interactions between functioning and the environment on both walking outcomes. Based on a previous study where environment x neighborhood income associations were found for Belgian older adults' moderate-to-vigorous physical activity, three-way functioning x environment x income interactions were examined for moderate-to-vigorous physical activity. Objectively-measured walkability moderated the association between functioning and transport walking; this positive association was only present in high-walkable neighborhoods. Moreover, a three-way interaction was observed for moderate-to-vigorous physical activity. Only in high-income, high-walkable neighborhoods, there was a positive association between functioning and moderate-to-vigorous physical activity. No

Relations between the school physical environment and school social capital with student physical activity levels

PubMed Central

2013-01-01

Background The physical and social environments at schools are related to students’ moderate-to-vigorous physical activity (MVPA) levels. The purpose of this study was to explore the interactive effects of the school physical environment and school social capital on the MVPA of students while at school. Methods Data from 18,875 grade 6–10 students from 331 schools who participated in the 2009/10 Canadian Health Behaviour in School-Aged Children survey were analyzed using multi-level regression. Students answered questions on the amount of time they spend in MVPA at school and on their school’s social capital. Administrator reports were used to create a physical activity related physical environment score. Results The school physical environment score was positively associated with student MVPA at school (β = 0.040, p < .005). The association between the school social capital and MVPA was also positive (β = 0.074, p < .001). The difference in physical environments equated to about 20 minutes/week of MVPA for students attending schools with the lowest number of physical environment features and about 40 minutes/week for students attending schools with the lowest school social capital scores by comparison to students attending schools with the highest scores. Conclusions The findings suggest that school social capital may be a more important factor in increasing students MVPA than the school physical environment. The results of this study may help inform interventions aimed at increasing student physical activity levels. PMID:24341628

Physical and relational bullying and victimization: Differential relations with adolescent dating and sexual behavior.

Dane, Andrew V; Marini, Zopito A; Volk, Anthony A; Vaillancourt, Tracy

2017-04-01

Taking an evolutionary psychological perspective, we investigated whether involvement in bullying as a perpetrator or victim was more likely if adolescents reported having more dating and sexual partners than their peers, an indication of greater engagement in competition for mates. A total of 334 adolescents (173 boys, 160 girls) between the ages of 12 and 16 years (M = 13.6, SD = 1.3), recruited from community youth organizations, completed self-report measures of physical and relational bullying and victimization, as well as dating and sexual behavior. As predicted, pure physical bullying was positively associated with the number of dating and sexual partners, primarily for adolescent boys. Adolescent girls with more dating partners had greater odds of being relational bully-victims, in line with predictions. Finally, adolescent girls with more sexual partners were at greater risk of being physically victimized by peers, and greater involvement with dating and sexual partners was associated with higher odds of being a physical bully-victim. Results are discussed with respect to evolutionary theory and research in which adolescent boys may display strength and athleticism through physical bullying to facilitate intersexual selection, whereas relational bullying may be employed as a strategy to engage in intrasexual competition with rivals for mates.

Letvak, Susan

2005-01-01

The nursing workforce is aging at an unprecedented rate yet little is known about the health and safety of older registered nurses (RNs). The survey reported here examined the relationships between demographic variables, job attributes (job satisfaction, control over practice, and job demands) and the physical and mental health and job-related injuries and health disorders of 308 nurses over the age of 50. Findings indicate that nurses with higher job satisfaction, higher control over practice, and lower job demands experienced increased physical health. Increasing age was positively correlated with mental health. Almost a quarter of older RNs experienced a job-related injury within the past 5 years, and over a third experienced job-related health problems. Nurses with higher job demands and those employed in hospital settings were more likely to have an injury. Overall, older RNs reported higher levels of physical and mental health than the national norm. Efforts must be made to keep older RNs healthy so we can retain them in the workforce.

Metal fabrication employs an estimated 3.1 million workers in the United States. The absence of machine guarding and related programs such as lockout/tagout may result in serious injury or death. The purpose of this study was to improve machine-related safety in small metal-fabrication businesses. We used a randomized trial with two groups: management only and management-employee. We evaluated businesses for the adequacy of machine guarding (machine scorecard) and related safety programs (safety audit). We provided all businesses with a report outlining deficiencies and prioritizing their remediation. In addition, the management-employee group received four one-hour interactive training sessions from a peer educator. We evaluated 40 metal-fabrication businesses at baseline and 37 (93%) one year later. Of the three nonparticipants, two had gone out of business. More than 40% of devices required for adequate guarding were missing or inadequate, and 35% of required safety programs and practices were absent at baseline. Both measures improved significantly during the course of the intervention. No significant differences in changes occurred between the two intervention groups. Machine-guarding practices and programs improved by up to 13% and safety audit scores by up to 23%. Businesses that added safety committees or those that started with the lowest baseline measures showed the greatest improvements. Simple and easy-to-use assessment tools allowed businesses to significantly improve their safety practices, and safety committees facilitated this process.

Effect of physical effort on mental workload of cyclists in real traffic in relation to age and use of pedelecs.

To improve cycling safety, insight is required into the factors that contribute to road safety of older cyclists. From the wide range of possible factors, this paper addresses the role of physical effort on mental workload of cyclists with the aim to investigate whether physical effort affects mental workload of cyclists in real traffic in a field experiment. Two instrumented bicycles, a conventional bicycle and a pedelec, were used. Mental workload of cyclists in two age groups - 30-45 years and 65 years and over - was measured by means of a secondary cognitive task requiring the detection and reaction to visual stimuli on a cycle route that varied in physical effort and task complexity. We expected physical effort to impair performance on the secondary task in complex traffic sections and not in simple sections, and that this impairment would be greater for older cyclists because of age related reduced muscle strength than for younger cyclists. We expected this impairment to be smaller if a pedelec was used. If such would be the case, this would indicate pedelecs to be beneficial for this older age group, because of a lower mental workload. Our study confirmed that increased physical effort in complex traffic sections deteriorated the detection of relevant stimuli in both age groups. Overall, older cyclists had longer reaction times and lower hit rates than younger cyclists. Mental workloads of cyclists are basically the same when cycling on a conventional bicycle or on a pedelec. In theory, pedelecs may be beneficial to reduce physical effort in cycling in order to maintain enough mental capacity to handle complex traffic situations. However, this study did not demonstrate these benefits. As pedelecs are often used for longer trips, by elderly with low muscle strength, future studies should also explore the effect of higher physical effort over longer periods of time, and also specifically in elderly with low muscle strength.

In the UK, increasing numbers of paid employees are over 60 years with further increases expected as the state pension age rises. Some concern surrounds possible increased work-related illness and accidents for people working beyond the age of 60. To identify the available evidence for health and safety risks of workers over age 60 years with respect to factors associated with injuries and accidents. Databases searched included PUBMED, OSHUpdate, National Institute for Occupational Safety and Health (NIOSHTIC-2), SafetyLit, the UK The Health and Safety Executive (HSELINE) and the Canadian Centre for Occupational Health and Safety until December 2009. Inclusion criteria were workers aged over 60 years. Findings were grouped into occupational accidents and injuries and individual and workplace factors that may have influenced risk of injury to the over-60s. Very little direct evidence was found concerning safety practices and health risks of workers over age 60. Some safety risks were associated with specific physical declines such as age-related hearing loss. Overall, these workers had fewer accidents and injuries but these were more likely to be serious or fatal when they occurred. There was no strong evidence that work patterns, including shift work or overtime, affected safety. Protective, compensatory strategies or experience may maintain safe working practices. Implications for health and safety risks cannot be assessed without longitudinal research on workforces with substantial numbers of workers over age 60 in order to address the healthy worker effect.

Little research is available concerning physical activity and its determinants in people with chronic neck pain. To explore the relation between kinesiophobia and physical activity and gender effect on these relations in people with chronic neck pain. Ninety-nine subjects (34 men and 65 women) with chronic neck pain were participated in the study. Pain intensity was assessed with Visual Analog Scale and kinesiophobia degree was determined by using Tampa Scale of Kinesiophobia. Level of physical activity was assessed with short form of the International Physical Activity Questionnaire. There was no statistically correlation between neck pain intensity and kinesiophobia degree (p= 0.246, r= 0.123) and physical activity level (p= 0.432, r= -0.083). It was also found that kinesiophobia degree was not correlated to physical activity level (p= 0.148, r= -0.153). There was a negative correlation between kinesiophobia degree and physical activity level only for women, not for men (p= 0.011, r= -0.318). Our results showed that although people with chronic neck pain reported higher pain intensity and fear of movement, pain intensity and kinesiophobia degree did not associate to their physical activity levels. It can be speculated that high kinesiophobia degrees cause low physical activity levels for women, but not for men.

Calway, R C

2001-01-01

Safety and risk management hazards are a fact of life for the medical practice, and the costs of these incidents can place the group at significant risk of liability. Good compliance and risk management programs help minimize these incidents, improve staff morale, increase a practice's visibility in the community, and positively affect the practice's financial and operational bottom line performance. Medical practices that implement effective safety and risk management programs can realize savings in staffing costs, operational efficiency, morale, insurance premiums, and improved third-party relationships while at the same time avoiding embarrassing risks, fines, and liability. This article outlines some of the most common safety and risk management-related deficiencies seen in medical practices today. The author explains how to remedy these deficiencies and provides a self-test tool to enable the reader to assess areas within his or her own practice in need of attention.

Associations between different types of physical activity and teachers’ perceived mental, physical, and work-related health

PubMed Central

2014-01-01

Background The teaching profession is characterized by high levels of stress and physical complaints, which might be improved through regular participation in physical activity (PA). However, the effect of PA on mental and physical health is not always consistent and depends on the type of PA performed. The aim of this study was to examine the mental, physical, and work-related health of Flemish secondary school teachers and identify the impact on those health variables by demographic and teaching-related factors and various types of PA. Methods This study included an online survey conducted across a representative sample of secondary school teachers (n = 1066, average age 40 years; 68 percent female). Level of PA and sitting time were estimated using the International Physical Activity Questionnaire, and perceived mental health and physical health were estimated using the Short Form 36. Work-related factors such as job satisfaction, occupational stress, and absenteeism were also collected. T-tests, ANOVAs, and linear regression analyses were performed. Results Flemish secondary school teachers have poorer perceived mental and physical health than a general healthy population. This difference is particularly evident among female teachers, who reported lower perceived health, more occupational stress, and more absent days compared to their male colleagues. Higher participation in leisure-time PA was associated with a more positive perceived health. In contrast, higher levels of occupational PA and sitting time had a negative impact on perceived health. Total amount of PA, total amount of moderate-to-vigorous PA, transportation-related PA, and PA at home were not associated to teachers’ perceived health. Conclusion Because secondary school teachers’ levels of perceived health are low, they are an important target group for interventions aiming to improve health. Only leisure-time PA was associated with more positive perceived health. This finding may

Fatigue is a serious problem for the majority of patients with cancer. In this context, several studies have shown benefits of physical activity during and following treatment. However, uncertainties remain regarding the optimal type and duration of physical activity. Therefore, this study examined the relationship between cancer-related fatigue and physical activity in the course of inpatient rehabilitation. Fatigue (Multidimensional Fatigue Inventory) and physical activity (Freiburg Questionnaire of Physical Activity) were assessed in a consecutive series of 35 patients with cancer attending oncological inpatient rehabilitation during a six-month study period. The three-week rehabilitation program included daily exercise therapy consisting of aerobic endurance training, moderate resistance training, coordination exercises, relaxation training and individual physiotherapy. At discharge, a significant improvement in each dimension of cancer-related fatigue (p=0.001-0.003) and a significant increase of physical activity levels (p=0.001) were observed. A small, but significant negative correlation was found between cancer-related fatigue and the level of physical activity (R=-0.438, p=0.004). The largest effects were associated with a weekly energy expenditure of 3000 kcal through physical activity. The results support a non-linear dose-response relationship between cancer-related fatigue and physical activity. Since this is the first study providing specific exercise recommendations for an effective treatment of cancer-related fatigue in the context of inpatient rehabilitation, further research is required to validate the observed trends.

Purpose Using a sample of 180 9-yr-old girls and their parents, this study examined (a) parents’ activity-related parenting strategies and similarities and differences in such strategies for mothers and fathers, and (b) links between activity-related parenting strategies and girls’ physical activity patterns. Methods Measures of girls’ physical activity included the Children’s Physical Activity scale, participation in organized sports, and physical fitness. We developed a questionnaire to assess ways in which parents promote physical activity among their children. Results Exploratory and confirmatory factor analyses identified two factors for each parent including logistic support of girls’ activity (i.e., enrolling girls in sports and driving them to events) and parents’ explicit modeling (i.e., the extent to which parents used their own behavior to encourage their daughters to be active). Mothers reported significantly higher levels of logistic support than fathers, whereas fathers reported higher levels of explicit modeling than mothers. Although mothers and fathers tended to report different methods of support, both methods were associated with higher physical activity among girls. Finally, girls reported significantly higher levels of physical activity when at least one parent reported high levels of overall support in comparison to no parents; no significant differences were identified for support from one versus two parents. Conclusion Results from this study indicate the positive contribution that parents can have on activity practices of their young daughters. PMID:12972881

Sophisticated Calculation of the 1oo4-architecture for Safety-related Systems Conforming to IEC61508

With the publication and enforcement of the standard IEC 61508 of safety related systems, recent system architectures have been presented and evaluated. Among a number of techniques and measures to the evaluation of safety integrity level (SIL) for safety-related systems, several measures such as reliability block diagrams and Markov models are used to analyze the probability of failure on demand (PFD) and mean time to failure (MTTF) which conform to IEC 61508. The current paper deals with the quantitative analysis of the novel 1oo4-architecture (one out of four) presented in recent work. Therefore sophisticated calculations for the required parameters are introduced. The provided 1oo4-architecture represents an advanced safety architecture based on on-chip redundancy, which is 3-failure safe. This means that at least one of the four channels have to work correctly in order to trigger the safety function.

Teaching Physics for Conceptual Understanding Exemplified for Einstein's Special Relativity

NASA Astrophysics Data System (ADS)

Undreiu, Lucian M.

2006-12-01

In most liberal arts colleges the prerequisites for College Physics, Introductory or Calculus based, are strictly related to Mathematics. As a state of fact, the majorities of the students perceive Physics as a conglomerate of mathematical equations, a collection of facts to be memorized and they regard Physics as one of the most difficult subjects. A change of this attitude towards Physics, and Science in general, is intrinsically connected with the promotion of conceptual understanding and stimulation of critical thinking. In such an environment, the educators are facilitators, rather than the source of knowledge. One good way of doing this is to challenge the students to think about what they see around them and to connect physics with the real world. Motivation occurs when students realize that what was learned is interesting and relevant. Visual teaching aids such as educational videos or computer simulations, as well as computer-assisted experiments, can greatly enhance the effectiveness of a science lecture or laboratory. Difficult topics can be discussed through animated analogies. Special Relativity is recognized as a challenging topic and is probably one of the most misunderstood theories of Physics. While understanding Special Relativity requires a detachment from ordinary perception and every day life notions, animated analogies can prove to be very successful in making difficult topics accessible.

Identifying the critical physical demanding tasks of paramedic work: Towards the development of a physical employment standard.

2017-11-01

Public safety related occupations including police, fire and military commonly apply physical employment standard (PES) to facilitate job matching, an approach to evaluate if candidates demonstrate acceptable physical capabilities as required to perform the job safely and effectively. In Canada, paramedics remain as one of the few public safety occupations without an evidence-based, validated PES. The purpose of this study was to document and describe the physical demands of paramedic work and to identify the most physically demanding tasks. These outcomes are essential to inform the design and development of an evidence-based PES for the paramedic sector. Physical demands of paramedic work were documented and described using a direct observation-based task analysis technique. Five paramedic's were trained to document the physical demands of their work, then applied their training to observe more than 90 calls over the course of 20 full 12-h work shifts. Physical demands data were then listed in a survey, administered service-wide, where 155 frontline paramedics identified critically demanding tasks and rank-ordered physical demands from not physically demanding to very strongly demanding. Critically important and physically demanding tasks were identified such as: transferring a patient; loading or unloading a stretcher in to or out of the ambulance; performing CPR; and, raising and lowering a stretcher. It is important that a paramedic-based PES evaluate a candidate's physical capabilities to perform the critical and physically demanding tasks identified in this study. Copyright © 2017 Elsevier Ltd.

2017-11-09

There has been increasing interest in examining the relationship between physician wellbeing and quality of patient care. However, few reviews have specifically focused on resident burnout and quality of patient care. The purpose of this systematic literature review of the current scientific literature is to address the question, "How does resident burnout affect the quality of healthcare related to the dimensions of acceptability and safety?" This systematic literature review uses a multi-step screening process of publicly available peer-reviewed studies from five electronic databases: (1) Medline Current, (2) Medline In-process, (3) PsycINFO, (4) Embase, and (5) Web of Science. The electronic literature search resulted in the identification of 4638 unique citations. Of these, 10 articles were included in the review. Studies were assessed for risk of bias. Of the 10 studies that met the inclusion criteria, eight were conducted in the US, one in The Netherlands, and one in Mexico. Eight of the 10 studies focused on patient safety. The results of these included studies suggest there is moderate evidence that burnout is associated with patient safety (i.e., resident self-perceived medical errors and sub-optimal care). There is less evidence that specific dimensions of burnout are related to acceptability (i.e., quality of care, communication with patients). The results of this systematic literature review suggest a relationship between patient safety and burnout. These results potentially have important implications for the medical training milieu because residents are still in training and at the same time are asked to teach students. The results also indicate a need for more evidence-based interventions that support continued research examining quality of care measures, especially as they relate to acceptability.

Objective To clarify the effects of mental health and physical function in association with colonoscopy-related pain. Methods The mental health and physical function were evaluated using the Japanese version of the SF-8 Health Survey questionnaire. Poor physical status was defined as a physical component summary (PCS) <40 and poor mental status as a mental component summary (MCS) <40. Pain was assessed using a visual analogue scale (VAS), with significant pain defined as VAS ≥70 mm and insignificant pain as VAS <70 mm. The background and colonoscopic findings were compared in patients with significant and insignificant pain. Patients This study evaluated consecutive Japanese patients who were positive on fecal occult blood tests and underwent total colonoscopy. Results Of the 100 patients, 23 had significant and 77 had insignificant colonoscopy-related pain. A multiple logistic regression analysis showed that MCS <40 [odds ratio (OR) 6.03; 95% confidence interval (CI) 1.41-25.9, p=0.0156], PCS <40 (OR 5.96; 95% CI 1.45-24.5, p=0.0133), and ≥300 seconds to reach the cecum (OR 4.13; 95% CI 1.16-14.7, p=0.0281) were independent risk factors for colonoscopy-related pain. Conclusion The mental health and physical function are important determinants of colonoscopy-related pain. Evaluating the mental health and physical function of patients prior to colonoscopy may effectively predict the degree of colonoscopy-related pain. PMID:28202858

Fusion power holds the promise of electricity production with a high degree of safety and low environmental impact. Favourable characteristics of fusion as an energy source provide the potential for this very good safety and environmental performance. But to fully realize the potential, attention must be paid in the design of a demonstration fusion power plant (DEMO) or a commercial power plant to minimize the radiological hazards. These hazards arise principally from the inventory of tritium and from materials that become activated by neutrons from the plasma. The confinement of these radioactive substances, and prevention of radiation exposure, are the primary goals of the safety approach for fusion, in order to minimize the potential for harm to personnel, the public, and the environment. The safety functions that are implemented in the design to achieve these goals are dependent on the performance of a range of materials. Degradation of the properties of materials can lead to challenges to key safety functions such as confinement. In this paper the principal types of material that have some role in safety are recalled. These either represent a potential source of hazard or contribute to the amelioration of hazards; in each case the related issues are reviewed. The resolution of these issues lead, in some instances, to requirements on materials specifications or to limits on their performance.

A growing body of research has examined the relationship between perceived neighborhood safety and parental encouragement for child physical activity (PA), yet these potential predictors have not been studied together to predict child outdoor PA. The purpose of this study is to examine these predictors and parent- and child-reported child outdoor PA. The Texas Childhood Obesity Research Demonstration study collected data from fifth-grade students attending 31 elementary schools across Austin and Houston and their parents (N = 748 parent-child dyads). Mixed-effects linear and logistic regressions stratified by gender and adjusted for sociodemographic covariates assessed associations among parental-perceived neighborhood safety, parental encouragement for child's outdoor PA, and parent- and child-reported child's outdoor PA. Parental-perceived neighborhood safety was significantly associated with encouraging outdoor PA (P = .01) and child-reported child's outdoor PA in boys, but not in girls. Significant associations were found between parental encouragement and child-reported outdoor PA for girls (P < .05) and parent-reported outdoor PA (P < .01) for boys and girls. Parent encouragement of PA and neighborhood safety are potential predictors of child outdoor PA and could be targeted in youth PA interventions.

The effects of a 2-year health-related school physical education program on standardized academic achievement scores was assessed in 759 children who completed Metropolitan Achievement Tests before and after the program. Schools were randomly assigned to condition: (a) Specialists taught the Sports, Play, and Active Recreation for Kids curriculum; (b) classroom teachers were trained to implement the curriculum; and (c) controls continued their usual programs. The Trained Teacher condition was superior to Control on Language, Reading, and Basic Battery. The Specialist condition was superior to Control on Reading, but inferior on Language. Despite devoting twice as many minutes per week to physical education as Controls, the health-related physical education program did not interfere with academic achievement. Health-related physical education may have favorable effects on students' academic achievement.

Background Because chronic kidney disease (CKD) is associated with muscle wasting, older adults with CKD are likely to have physical function deficits. Physical activity can improve these deficits, but whether CKD attenuates the benefits is unknown. Our objective was to determine if CKD modified the effect of a physical activity intervention in older adults. Methods This is an exploratory analysis of the LIFE-P study, which compared a 12-month physical activity program (PA) to a successful aging education program (SA) in older adults. CKD was defined as a baseline eGFR < 60 mL/min/1.73 m2. We examined the Short Physical Performance Battery (SPPB) at baseline, 6 and 12 months. Secondary outcomes included serious adverse events (SAE) and adherence to intervention frequency. Linear mixed models were adjusted for age, sex, diabetes, hypertension, CKD, intervention, site, visit, baseline SPPB, and interactions of intervention and visit and of intervention, visit, and baseline CKD. Results The sample included 368 participants. CKD was present in 105 (28.5%) participants with a mean eGFR of 49.2 ± 8.1 mL/min/1.73 m2. Mean SPPB was 7.38 ± 1.41 in CKD participants; 7.59 ± 1.44 in those without CKD (p = 0.20). For CKD participants in PA, 12-month SPPBs increased to 8.90 (95% CI 8.32, 9.47), while PA participants without CKD increased to 8.40 (95% CI 8.01, 8.79, p = 0.43). For CKD participants in SA, 12-month SPPBs increased to 7.67 (95% CI 7.07, 8.27), while participants without CKD increased to 8.12 (95% CI 7.72, 8.52, p = 0.86). Interaction between CKD and intervention was non-significant (p = 0.88). Number and type of SAEs were not different between CKD and non-CKD participants (all p > 0.05). In PA, adherence for CKD participants was 65.5 ± 25.4%, while for those without CKD was 74.0 ± 22.2% (p = 0.12). Conclusion Despite lower adherence, older adults with CKD likely derive clinically meaningful benefits from physical activity with no apparent impact on safety

Do you see what I see? Effects of national culture on employees' safety-related perceptions and behavior.

Growing international trade and globalization are increasing the cultural diversity of the modern workforce, which often results in migrants working under the management of foreign leadership. This change in work arrangements has important implications for occupational health and safety, as migrant workers have been found to be at an increased risk of injuries compared to their domestic counterparts. While some explanations for this discrepancy have been proposed (e.g., job differences, safety knowledge, and communication difficulties), differences in injury involvement have been found to persist even when these contextual factors are controlled for. We argue that employees' national culture may explain further variance in their safety-related perceptions and safety compliance, and investigate this through comparing the survey responses of 562 Anglo and Southern Asian workers at a multinational oil and gas company. Using structural equation modeling, we firstly established partial measurement invariance of our measures across cultural groups. Estimation of the combined sample structural model revealed that supervisor production pressure was negatively related to willingness to report errors and supervisor support, but did not predict safety compliance behavior. Supervisor safety support was positively related to both willingness to report errors and safety compliance. Next, we uncovered evidence of cultural differences in the relationships between supervisor production pressure, supervisor safety support, and willingness to report errors; of note, among Southern Asian employees the negative relationship between supervisor production pressure and willingness to report errors was stronger, and for supervisor safety support, weaker as compared to the model estimated with Anglo employees. Implications of these findings for safety management in multicultural teams within the oil and gas industry are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Martins, Nicole

2013-12-01

An experiment was conducted with 150 children (mean age=10.1years) in third to fifth grades to test whether exposure to different forms of aggression in the media affected hostile attributional biases in response to different forms of provocation scenarios. Children were randomly assigned to watch a clip containing physical aggression, relational aggression, or no aggression. After exposure, children were asked to respond to a series of written provocation scenarios where a character caused some form of harm (instrumental or relational) to a target person, but the intent of the provocateur was ambiguous. Results revealed that exposure to relationally aggressive portrayals resulted in a hostile attributional bias in response to relational scenarios, whereas exposure to portrayals of physical aggression was associated with a hostile attributional bias in response to instrumental scenarios. Moreover, these biases were shown to be specific to the exposure condition (physical or relational) and not simply associated with exposure to aggression in general. The findings are discussed in terms of the general aggression model and children's social information processing. Copyright © 2013 Elsevier Inc. All rights reserved.

Migrant women are over-represented in the sex industry, and migrant sex workers experience disproportionate health inequities, including those related to health access, HIV and sexually transmitted infections (STIs), and violence. Despite calls for occupational sex work interventions situated in labour rights frameworks, there remains a paucity of evidence pertaining to migrant sex workers' needs and realities, particularly within Mexico and Central America. This study investigated migrant sex workers' narratives regarding the ways in which structural features of work environments shape vulnerability and agency related to HIV/STI prevention and violence at the Guatemala-Mexico border. Drawing on theoretical perspectives on risk environments and structural determinants of HIV in sex work, we analyzed in-depth interviews, focus groups, and ethnographic fieldwork conducted with 39 migrant sex workers in indoor work environments between 2012 and 2015 in Tecún Umán, Guatemala. Participant narratives revealed the following intersecting themes to be most closely linked to safety and agency to engage in HIV/STI prevention: physical features of indoor work environments (e.g., physical layout of venue, proximity to peers and third parties); social norms and practices for alcohol use within the workplace; the existence and nature of management practices and policies on health and safety practices; and economic influences relating to control over earnings and clients. Across work environments, health and safety were greatly shaped by human rights concerns stemming from workplace interactions with police, immigration authorities, and health authorities. Physical isolation, establishment norms promoting alcohol use, restricted economic agency, and human rights violations related to sex work policies and immigration enforcement were found to exacerbate risks. However, some establishment policies and practices promoted 'enabling environments' for health and safety, supporting

Physical Therapists' Views and Experiences of Pregnancy-Related Low Back Pain and the Role of Acupuncture: Qualitative Exploration

2015-01-01

Background Low back pain is often accepted as a “normal” part of pregnancy. Despite research suggesting that quality of life for women who are pregnant is adversely affected, most are advised to self-manage. Although the use of acupuncture for the management of persistent nonspecific low back pain has been recommended in recent UK national guidelines, its use in the management of pregnancy-related low back pain remains limited. Objectives This study aimed to explore the perceptions and experiences of physical therapists involved in treating women who are pregnant and have low back pain with the objective of informing the pretrial training program for a pilot randomized trial (Evaluating Acupuncture and Standard care for pregnant womEn with Back pain [EASE Back]). Design A qualitative phenomenological method with purposive sampling was used in the study. Methods Three focus groups and 3 individual semistructured interviews were undertaken, and an iterative exploratory thematic analysis was performed. To ensure transparency of the research process and the decisions made, an audit trail was created. Results Twenty-one physical therapists participated, and emergent issues included: a lack of experience in treating pregnancy-related complaints, mixed messages from previous acupuncture education, a mistrust of the current evidence for acupuncture safety and effectiveness, and personal and professional fear of causing harm. Conclusions The findings suggest that UK physical therapists are reluctant to use acupuncture in the management of pregnancy-related low back pain. The explanations for these findings include perceived lack of knowledge and confidence, as well as a pervasive professional culture of caution, particularly fears of inducing early labor and of litigation. These findings have been key to informing the content of the training program for physical therapists delivering acupuncture within the pilot EASE Back trial. PMID:25929530

Obesity represents a major public health problem worldwide. In Mexico, overweight and obesity have increased dramatically, affecting 26% of school-aged children. The aim of this study was to explore perceptions and practices of key obesity determinants among parents of preschool children attending child care centers. We conducted five focus groups with 38 parents from six Mexico City child care centers. Inquiry topics were 1) childhood obesity causes and consequences; 2) child feeding practices at the child care center and home; 3) healthful and unhealthful foods for young children; 4) significance of physical activity in childhood; and 5) physical activity-promoting factors and barriers. We analyzed these data using content analysis. We identified a number of barriers to healthful eating, including parental time constraints, permissive feeding styles, unhealthful food preparation practices, lack of knowledge about nutrition, food advertisement, and high availability of unhealthful foods in public places. Facilitators to healthful eating included recognition of childhood overweight prevention and consequences, and healthy food choices. Main barriers to childhood physical activity included influence of young family members to play video games, parental time constraints, street safety, low access to sports facilities, and insufficient communication with child care centers. Understanding parental views and perceptions of the main factors influencing preschoolers' weight-related behavior can inform home-based or environmental interventions that support healthful eating and regular physical activity.

Health care workers are exposed to psychosocial work factors. Autonomy and social support are psychosocial work factors that are related to stress, and are argued to largely result from the psychosocial safety climate within organisations. This study aimed to assess to what extent the relation between psychosocial safety climate and stress in health care workers can be explained by autonomy and social support. In a cross-sectional study, psychosocial safety climate, stress, autonomy, co-worker support, and supervisor support were assessed using questionnaires, in a sample of health care workers (N = 277). Linear mixed models analyses were performed to assess to what extent social support and autonomy explained the relation between psychosocial safety climate and stress. A lower psychosocial safety climate score was associated with significantly higher stress (B = -0.21, 95% CI = -0.27 - -0.14). Neither co-worker support, supervisor support, nor autonomy explained the relation between psychosocial safety climate and stress. Taken together, autonomy and both social support measures diminished the relation between psychosocial safety climate and stress by 12% (full model: B = -0.18, 95% CI = -0.25 - -0.11). Autonomy and social support together seemed to bring about a small decrease in the relation between psychosocial safety climate and stress in health care workers. Future research should discern whether other psychosocial work factors explain a larger portion of this relation.

To assess the effects of medicinal plants (MPs) or related natural products (RNPs) on fibromyalgia (FM) patients, we evaluate the possible benefits and advantages of MP or RNP for the treatment of FM based on eight randomized placebo-controlled trials (RCTs) involving 475 patients. The methodological quality of all studies included was determined according to JADAD and “Risk of Bias” with the criteria in the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0. Evidence suggests significant benefits of MP or RNP in sleep disruption, pain, depression, joint stiffness, anxiety, physical function, and quality of life. Our results demonstrated that MP or RNP had significant effects on improving the symptoms of FM compared to conventional drug or placebo; longer tests are required to determine the duration of the treatment and characterize the long-term safety of using MP, thus suggesting effective alternative therapies in the treatment of pain with minimized side effects.

Transformational and passive leadership as cross-level moderators of the relationships between safety knowledge, safety motivation, and safety participation.

PubMed

Jiang, Lixin; Probst, Tahira M

2016-06-01

While safety knowledge and safety motivation are well-established predictors of safety participation, less is known about the impact of leadership styles on these relationships. The purpose of the current study was to examine whether the positive relationships between safety knowledge and motivation and safety participation are contingent on transformational and passive forms of safety leadership. Using multilevel modeling with a sample of 171 employees nested in 40 workgroups, we found that transformational safety leadership strengthened the safety knowledge-participation relationship, whereas passive leadership weakened the safety motivation-participation relationship. Under low transformational leadership, safety motivation was not related to safety participation; under high passive leadership, safety knowledge was not related to safety participation. These results are discussed in light of organizational efforts to increase safety-related citizenship behaviors. Copyright © 2016 Elsevier Ltd and National Safety Council. All rights reserved.

The relative cost of children's physical play.

PubMed

Pellegrini; Horvat; Huberty

1998-04-01

There has been a long-standing debate regarding the functions of play during childhood. An important, but neglected, first step in this debate entails documenting the costs associated with play. In this study we analysed energetic costs (expressed in terms of caloric expenditure) associated with physical play in four field experiments of play in primary school children. Experiment 1 established the concurrent validity of an observational check list to estimate caloric expenditure of children's physical play. Experiment 2 compared caloric expenditure of the play (defined as all behaviour exhibited during play time) for two age groups of children during playtime outdoors and during indoor sedentary activity; caloric expenditure of outdoor activity was greater and was significantly correlated with ambient temperature. In experiment 3, children were observed during indoor play to control for the influence of ambient temperature. Outdoor physical play was more energetically costly than indoor physical play. In experiment 4, children's behaviour was observed outdoors and caloric expenditure for play, games and other activities was compared. Physical play was more costly than other forms of behaviour and games. Estimates of total energetic costs of play ranged from 6 to 15%. Results are discussed in terms of the relatively low caloric costs of play. Copyright 1998 The Association for the Study of Animal Behaviour.

Objective: To examine whether engagement in physical activity might favorably alter the age-dependent evolution of Alzheimer disease (AD)-related brain and cognitive changes in a cohort of at-risk, late-middle-aged adults. Methods: Three hundred seventeen enrollees in the Wisconsin Registry for Alzheimer's Prevention underwent T1 MRI; a subset also underwent 11C-Pittsburgh compound B–PET (n = 186) and 18F-fluorodeoxyglucose–PET (n = 152) imaging. Participants' responses on a self-report measure of current physical activity were used to classify them as either physically active or physically inactive based on American Heart Association guidelines. They also completed a comprehensive neuropsychological battery. Covariate-adjusted regression analyses were used to test whether the adverse effect of age on imaging and cognitive biomarkers was modified by physical activity. Results: There were significant age × physical activity interactions for β-amyloid burden (p = 0.014), glucose metabolism (p = 0.015), and hippocampal volume (p = 0.025) such that, with advancing age, physically active individuals exhibited a lesser degree of biomarker alterations compared with the physically inactive. Similar age × physical activity interactions were also observed on cognitive domains of Immediate Memory (p = 0.042) and Visuospatial Ability (p = 0.016). In addition, the physically active group had higher scores on Speed and Flexibility (p = 0.002) compared with the inactive group. Conclusions: In a middle-aged, at-risk cohort, a physically active lifestyle is associated with an attenuation of the deleterious influence of age on key biomarkers of AD pathophysiology. However, because our observational, cross-sectional design cannot establish causality, randomized controlled trials/longitudinal studies will be necessary for determining whether midlife participation in structured physical exercise forestalls the development of AD and related disorders in later life.

Hospital safety climate and safety behavior: A social exchange perspective.

PubMed

Ancarani, Alessandro; Di Mauro, Carmela; Giammanco, Maria D

Safety climate is considered beneficial to the improvement of hospital safety outcomes. Nevertheless, the relations between two of its key constituents, namely those stemming from leader-subordinate relations and coworker support for safety, are still to be fully ascertained. This article uses the theoretical lens of Social Exchange Theory to study the joint impact of leader-member exchange in the safety sphere and coworker support for safety on safety-related behavior at the hospital ward level. Social exchange constructs are further related to the existence of a shame-/blame-free environment, seen as a potential antecedent of safety behavior. A cross-sectional study including 166 inpatients in hospital wards belonging to 10 public hospitals in Italy was undertaken to test the hypotheses developed. Hypothesized relations have been analyzed through a fully mediated multilevel structural equation model. This methodology allows studying behavior at the individual level, while keeping into account the heterogeneity among hospital specialties. Results suggest that the linkage between leader support for safety and individual safety behavior is mediated by coworker support on safety issues and by the creation of a shame-free environment. These findings call for the creation of a safety climate in which managerial efforts should be directed not only to the provision of new safety resources and the enforcement of safety rules but also to the encouragement of teamwork and freedom to report errors as ways to foster the capacity of the staff to communicate, share, and learn from each other.

Nurse educators must adjust curricula to meet the dynamic and critical changes in the health care environment, and to recognize the risk of injury our educational approach has on safety, team effectiveness, and culture change. Interprofessional collaboration and simulation are key components in the preparation of our students. Utilizing the interprofessional alliance model, an experience to promote collaborative relationships among nursing and physical therapy (PT) students to improve patient and caregiver safety was developed. Through this model, PT students taught safe patient-handling skills in a simulated setting to undergraduate nursing students. The majority of nursing students (N=351) from 2009–2014 strongly agreed or agreed that they were confident in the skills taught by the PT students and provided an overall course rating of outstanding or above average. This educational model, which includes simulation and safe patient handling, was a valuable addition to the curriculum, reinforcing the significance of developing collaborative relationships.

Fall-related concern strongly correlates to activity avoidance in older people. In this complex phenomenon, different terminology and instruments are often used interchangeably. Three main concepts make up fall-related concerns: fear of falling, consequence concern, and falls self-efficacy. It is suggested that fall-related concerns are mediated by psychological and physical factors. Our aims were to describe the prevalence of fall-related concerns and find explanatory factors for its most studied concept-falls self-efficacy-in an older population. We executed a cross-sectional study on a random sample of 153 community-dwelling older people (70 years or older). We used validated and reliable instruments as well as structured interviews to gather data on the three concepts of fall-related concerns and possible mediating factors. We then calculated descriptive statistics on prevalence and regression models for the total group, and men and women, separately. 70% of the total sample (80% of women and 53% of men) reported at least one of the three concepts of fall-related concern. For the total sample, fear of falling, morale, and physical performance were associated factors with falls self-efficacy. For women, the number of prescription medications was added. For men, physical performance and concerns for injury were associated. Fall-related concern is prevalent in large proportions with higher prevalence for women than for men. Important factors are fear of falling, morale, and physical performance. Gender differences in the emergence and variance of fall-related concern and the relation between physical performance and fall-related concern should be targeted in future research endeavors.

Patient safety--worker safety: building a culture of safety to improve healthcare worker and patient well-being.

PubMed

Yassi, Annalee; Hancock, Tina

2005-01-01

Patient safety within the Canadian healthcare system is currently a high national priority, which merits a comprehensive understanding of the underlying causes of adverse events. Not least among these is worker health and safety, which is linked to patient outcomes. Healthcare workers have a high risk of workplace injuries and more mental health problems than most other occupational groups. Many healthcare professionals feel fatigued, stressed, in pain, or at risk of illness or injury-factors they feel impede their ability to provide consistent quality care. With this background, the Occupational Health and Safety Agency for Healthcare (OHSAH) in British Columbia, jointly governed by healthcare unions and healthcare employers, launched several major initiatives to improve the healthcare workplace. These included the promotion of safe patient handling, adaptive clothing, scheduled toileting, stroke management training, measures to improve management of aggressive behaviour and, of course, infection control-all intended to improve the safety of workers, but also to improve patient safety and quality of care. Other projects also explicitly promoting physical and mental health at work, as well as patient safety are also underway. Results of the projects are at various stages of completion, but ample evidence has already been obtained to indicate that looking after the well-being of healthcare workers results in safer and better quality patient care. While more research is needed, our work to date suggests that a comprehensive systems approach to promoting a climate of safety, which includes taking into account workplace organizational factors and physical and psychological hazards for workers, is the best way to improve the healthcare workplace and thereby patient safety.

In the United States, approximately 236,000 people work in 37,600 auto collision-repair businesses. Workers in the collision-repair industry may be exposed to a wide range of physical and chemical hazards. This manuscript examines the relationship of safety climate as reported by collision repair shop workers and owners to: (1) an independent business safety assessment, and (2) employee self-reported work practices. The study was conducted in the Twin Cities metropolitan area. A total of 199 workers from 49 collision shops completed a survey of self-reported work practices and safety climate. Surveys were completed by an owner or manager in all but three shops. In general, self-reported work practices were poor. Workers' scores on safety climate were uniformly lower than those of owners. For workers, there was no correlation between how well the business scored on an independent audit of business safety practices and the safety climate measures they reported. For owners, however, there was a positive correlation between safety climate scores and the business safety assessment. For workers, safety rules and procedures were associated with improved work practices for those engaged in both painting-related and body technician-related activities. The enforcement of safety rules and procedures emerged as a strong factor positively affecting self-reported work practices. These findings identify a simple, cost effective path to reducing hazards in small workplaces. © 2013 Wiley Periodicals, Inc.

Cognitive impairment after critical illness is common and debilitating. We developed a cognitive therapy program for critically ill patients and assessed the feasibility and safety of administering combined cognitive and physical therapy early during a critical illness. We randomized 87 medical and surgical ICU patients with respiratory failure and/or shock in a 1:1:2 manner to three groups: usual care, early once-daily physical therapy, or early once-daily physical therapy plus a novel, progressive, twice-daily cognitive therapy protocol. Cognitive therapy included orientation, memory, attention, and problem-solving exercises, and other activities. We assessed feasibility outcomes of the early cognitive plus physical therapy intervention. At 3 months, we also assessed cognitive, functional, and health-related quality of life outcomes. Data are presented as median (interquartile range) or frequency (%). Early cognitive therapy was a delivered to 41/43 (95%) of cognitive plus physical therapy patients on 100% (92-100%) of study days beginning 1.0 (1.0-1.0) day following enrollment. Physical therapy was received by 17/22 (77%) of usual care patients, by 21/22 (95%) of physical therapy only patients, and 42/43 (98%) of cognitive plus physical therapy patients on 17% (10-26%), 67% (46-87%), and 75% (59-88%) of study days, respectively. Cognitive, functional, and health-related quality of life outcomes did not differ between groups at 3-month follow-up. This pilot study demonstrates that early rehabilitation can be extended beyond physical therapy to include cognitive therapy. Future work to determine optimal patient selection, intensity of treatment, and benefits of cognitive therapy in the critically ill is needed.

Background Compliant flooring, broadly defined as flooring systems or floor coverings with some level of shock absorbency, may reduce the incidence and severity of fall-related injuries in older adults; however, a lack of synthesized evidence may be limiting widespread uptake. Methods Informed by the Arksey and O’Malley framework and guided by a Research Advisory Panel of knowledge users, we conducted a scoping review to answer: what is presented about the biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety associated with compliant flooring systems that aim to prevent fall-related injuries in healthcare settings? We searched academic and grey literature databases. Any record that discussed a compliant flooring system and at least one of biomechanical efficacy, clinical effectiveness, cost-effectiveness, or workplace safety was eligible for inclusion. Two independent reviewers screened and abstracted records, charted data, and summarized results. Results After screening 3611 titles and abstracts and 166 full-text articles, we included 84 records plus 56 companion (supplementary) reports. Biomechanical efficacy records (n = 50) demonstrate compliant flooring can reduce fall-related impact forces with minimal effects on standing and walking balance. Clinical effectiveness records (n = 20) suggest that compliant flooring may reduce injuries, but may increase risk for falls. Preliminary evidence suggests that compliant flooring may be a cost-effective strategy (n = 12), but may also result in increased physical demands for healthcare workers (n = 17). Conclusions In summary, compliant flooring is a promising strategy for preventing fall-related injuries from a biomechanical perspective.

Working Safely at Some Times and Unsafely at Others: A Typology and Within-Person Process Model of Safety-Related Work Behaviors.

PubMed

Beus, Jeremy M; Taylor, William D

2017-06-22

Why do individuals choose to work safely in some instances and unsafely in others? Though this inherently within-person question is straightforward, the preponderance of between-person theory and research in the workplace safety literature is not equipped to answer it. Additionally, the limited way in which safety-related behaviors tend to be conceptualized further restricts understanding of why individuals vary in their safety-related actions. We use a goal-focused approach to conceptually address this question of behavioral variability and contribute to workplace safety research in 2 key ways. First, we establish an updated typology of safety-related behaviors that differentiates behaviors based on goal choice (i.e., safe vs. unsafe behaviors), goal-directedness (i.e., intentional vs. unintentional behaviors), and the means of goal pursuit (i.e., commission vs. omission and promotion vs. prevention-focused behaviors). Second, using an expectancy-value theoretical framework to explain variance in goal choice, we establish within-person propositions stating that safety-related goal choice and subsequent behaviors are a function of the target of safety-related behaviors, the instrumentality and resource requirement of behaviors, and the perceived severity, likelihood, and immediacy of the threats associated with behaviors. Taken together, we define what safety-related behaviors are, explain how they differ, and offer propositions concerning when and why they may vary within-persons. We explore potential between-person moderators of our theoretical propositions and discuss the practical implications of our typology and process model of safety-related behavior.

Objective: Methods to identify and study safety risks of electronic health records (EHRs) are underdeveloped and largely depend on limited end-user reports. “Safety huddles” have been found useful in creating a sense of collective situational awareness that increases an organization’s capacity to respond to safety concerns. We explored the use of safety huddles for identifying and learning about EHR-related safety concerns. Design: Data were obtained from daily safety huddle briefing notes recorded at a single midsized tertiary-care hospital in the United States over 1 year. Huddles were attended by key administrative, clinical, and information technology staff. We conducted a content analysis of huddle notes to identify what EHR-related safety concerns were discussed. We expanded a previously developed EHR-related error taxonomy to categorize types of EHR-related safety concerns recorded in the notes. Results: On review of daily huddle notes spanning 249 days, we identified 245 EHR-related safety concerns. For our analysis, we defined EHR technology to include a specific EHR functionality, an entire clinical software application, or the hardware system. Most concerns (41.6%) involved “EHR technology working incorrectly,” followed by 25.7% involving “EHR technology not working at all.” Concerns related to “EHR technology missing or absent” accounted for 16.7%, whereas 15.9% were linked to “user errors.” Conclusions: Safety huddles promoted discussion of several technology-related issues at the organization level and can serve as a promising technique to identify and address EHR-related safety concerns. Based on our findings, we recommend that health care organizations consider huddles as a strategy to promote understanding and improvement of EHR safety. PMID:28031286

Background Second victim experiences can affect the well-being of healthcare providers and compromise patient safety. Many factors associated with improved coping afer patient safety event involvement are also components of a strong patient safety culture, so that supportive patient safety cultures may reduce second victim–related trauma. A cross-sectional survey study was conducted to assess the influence of patient safety culture on second victim–related distress, in which associations among patient safety culture dimensions, organizational support, and second victim distress were investigated. Methods The Agency for Healthcare Research and Quality (AHRQ) Hospital Survey on Patient Safety Culture (HSOPSC) and the Second Victim Experience and Support Tool (SVEST), which was developed to assess organizational support and personal and professional distress after involvement in a patient safety event, were administered to nurses involved in direct patient care. Results Of 358 nurses, 155 (41%) responded, of whom 144 completed both surveys. Hierarchical linear regression demonstrated that the patient safety culture survey dimension nonpunitive response to errors was significantly associated with reductions in the second victim survey dimensions psychological, physical, and professional distress (p <.001). As a mediator, organizational support fully explained the nonpunitive response to errors–physical distress and nonpunitive response to errors–professional distress relationships and partially explained the nonpunitive response to error–psychological distress relationship. Conclusions A nonpunitive response to errors may mitigate the negative effects of involvement in a patient safety event by encouraging supportive interactions. Also, perceptions of second victim–related distress may be less severe when hospital cultures are characterized by nonpunitive response to errors.

The Safety of Physically Disabled Drivers

Ysander, Lars

1966-01-01

Four hundred and ninety-four disabled drivers, the majority with loss of function in the legs usually as the result of poliomyelitis or amputations, have been studied with respect to the frequency of traffic accidents and serious traffic offences during a 10-year period. Traffic accidents which may have been caused by their disability occurred in only three (0·6%) of the total number of drivers investigated. In all three cases the driver had loss of function in the right leg. A comparison was made between the investigation series and a control series identical as regards sex, age, and licence-holding period but with a shorter exposure to traffic than the investigation series. The frequency of traffic accidents amounted to 7·1% in both series, and the frequency of serious traffic offences was 12·2% in the investigation series and 14·8% in the control series. Disabled drivers are not an increased hazard in traffic. The compensatory technical modifications to the vehicle which are generally adopted appeared to be adequate. However, there was a relatively increased frequency of accidents among drivers with loss of function in the right leg or right arm. An improvement of the technical modifications applied in these cases might result in a further reduction of the road-safety risks. PMID:4223486

Purpose Four forms of school bullying behaviors among US adolescents and their association with socio-demographic characteristics, parental support and friends were examined. Methods Data were obtained from the Health Behavior in School-Aged Children (HBSC) 2005 Survey, a nationally-representative sample of grades 6 to 10 (N = 7182). The Olweus Bully/Victim Questionnaire was used to measure physical, verbal and relational forms of bullying. Two items were added using the same format to measure cyber bullying. For each form, four categories were created: bully, victim, bully-victim, and not involved. Multinomial logistic regressions were applied, with socio-demographic variables, parental support and number of friends as predictors. Results Prevalence rates of having bullied others or having been bullied at school for at least once in the last 2 months were 20.8% physically, 53.6% verbally, 51.4% socially or 13.6% electronically. Boys were more involved in physical or verbal bullying, while girls were more involved in relational bullying. Boys were more likely to be cyber bullies, while girls were more likely to be cyber victims. African-American adolescents were involved in more bullying (physical, verbal or cyber) but less victimization (verbal or relational). Higher parental support was associated with less involvement across all forms and classifications of bullying. Having more friends was associated with more bullying and less victimization for physical, verbal and relational forms, but was not associated with cyber bullying. Conclusions Parental support may protect adolescents from all four forms of bullying. Friends associate differentially with traditional and cyber bullying. Results indicate that cyber bullying has a distinct nature from traditional bullying. PMID:19766941

Illness-related absenteeism is a major threat to work productivity. Our objective was to assess the relationship between physical activity and unplanned illness-related absenteeism from work. We implemented physical activity program for sedentary non-clinician employees of a tertiary medical center. Financial rewards were available for reaching accelerometer-measured ambulatory physical activity goals over a 24-week period. We categorized participants into three groups based on mean levels of physical activity: low (0-74 min/week), medium (75-149 min/week) and meeting CDC guidelines (≥150 min/week). We built a multivariable Poisson regression model to evaluate the relationship between physical activity and rates of unplanned illness-related absenteeism. The sample consisted of 292 employees who participated in the program. Their mean age was 38 years (SD 11), 83% were female, and 38% were obese. Over the 24 intervention weeks, participants engaged in a mean of 90 min/week (SD 74) of physical activity and missed a mean of 14 hours of work (SD 38) due to illness. Unplanned absenteeism due to illness was associated with physical activity. As compared to the group meeting CDC guidelines, in multivariable analyses those in the medium physical activity group had a 2.4 (95% CI 1.3-4.5) fold higher rate of illness-related absenteeism and those in the lowest physical activity group had a 3.5 (95% CI 1.7-7.2) fold higher rate of illness-related absenteeism. Less physical activity was associated with more illness-related absenteeism. Workforce-based interventions to increase physical activity may thus be a promising vehicle to reduce unplanned illness-related absenteeism.

Decreased physical capacity, weight loss, fat-free mass depletion and systemic inflammation are frequently observed in patients with chronic obstructive pulmonary disease (COPD). Our aim was to examine relations between physical capacity, nutritional status, systemic inflammation and disease severity in COPD. Forty nine patients with moderate to severe COPD were included in the study. Spirometry was preformed. Physical capacity was determined by a progressive symptom limited cycle ergo meter test, incremental shuttle walking test, 12-minute walk distance and hand grip strength test. Nutritional status was investigated by anthropometric measurements, (weight, height, arm and leg circumferences and skinfold thickness) and bioelectrical impedance assessment was performed. Blood samples were analyzed for C-reactive protein (CRP) and fibrinogen. Working capacity was positively related to forced expiratory volume in 1 s (FEV(1) ) (p < 0.001), body mass index and fat free mass index (p = 0.01) and negatively related to CRP (p = 0.02) and fibrinogen (p = 0.03). Incremental shuttle walk test was positively related to FEV(1) (p < 0.001) and negatively to CRP (p = 0.048). Hand grip strength was positively related to fat free mass index, and arm and leg circumferences. Fifty to 76% of the variation in physical capacity was accounted for when age, gender, FEV(1) , fat free mass index and CRP were combined in a multiple regression model. Physical capacity in chronic obstructive pulmonary disease is related to lung function, body composition and systemic inflammation. A depiction of all three aspects of the disease might be important when targeting interventions in chronic obstructive pulmonary disease. © 2010 Blackwell Publishing Ltd.

Allelic Variation of Risk for Anxiety Symptoms Moderates the Relation Between Adolescent Safety Behaviors and Social Anxiety Symptoms

Social anxiety often develops in adolescence, and precedes the onset of depression and substance use disorders. The link between social anxiety and use of behaviors to minimize distress in social situations (i.e., safety behaviors) is strong and for some patients, this link poses difficulty for engaging in, and benefiting from, exposure-based treatment. Yet, little is known about whether individual differences may moderate links between social anxiety and safety behaviors, namely variations in genetic alleles germane to anxiety. We examined the relation between adolescent social anxiety and expressions of safety behaviors, and whether allelic variation for anxiety moderates this relation. Adolescents (n=75; ages 14–17) were recruited from two larger studies investigating measurement of family relationships or adolescent social anxiety. Adolescents completed self-report measures about social anxiety symptoms and use of safety behaviors. They also provided saliva samples to assess allelic variations for anxiety from two genetic polymorphisms (BDNF rs6265; TAQ1A rs1800497). Controlling for adolescent age and gender, we observed a significant interaction between social anxiety symptoms and allelic variation (β=0.37, t=2.41, p=.02). Specifically, adolescents carrying allelic variations for anxiety evidenced a statistically significant and relatively strong positive relation between social anxiety symptoms and safety behaviors (β=0.73), whereas adolescents not carrying allelic variation evidenced a statistically non-significant and relatively weak relation (β=0.22). These findings have important implications for treating adolescent social anxiety, in that we identified an individual difference variable that can be used to identify people who evidence a particularly strong link between use of safety behaviors and expressing social anxiety.

Childers, A B; Walsh, B

1996-07-23

Preharvest food safety is essential for the protection of our food supply. The production and transport of livestock and poultry play an integral part in the safety of these food products. The goals of this safety assurance include freedom from pathogenic microorganisms, disease, and parasites, and from potentially harmful residues and physical hazards. Its functions should be based on hazard analysis and critical control points from producer to slaughter plant with emphasis on prevention of identifiable hazards rather than on removal of contaminated products. The production goal is to minimize infection and insure freedom from potentially harmful residues and physical hazards. The marketing goal is control of exposure to pathogens and stress. Both groups should have functional hazard analysis and critical control points management programs which include personnel training and certification of producers. These programs must cover production procedures, chemical usage, feeding, treatment practices, drug usage, assembly and transportation, and animal identification. Plans must use risk assessment principles, and the procedures must be defined. Other elements would include preslaughter certification, environmental protection, control of chemical hazards, live-animal drug-testing procedures, and identification of physical hazards.

This article aims to understand the incident patterns in relation to different types of spaces within a psychiatric unit, which are discussed using the five levels of safety framework. Implementing measures to improve patient safety is essential particularly in a psychiatric hospital, where limited research has been conducted on inpatient safety. Therefore, this article aims to understand the incident patterns from the lens of the five levels of safety framework, which categorizes spaces according to the level of patient supervision in psychiatric facilities, as follows: service areas, corridors, dayrooms, patient rooms and bathrooms, seclusions and admissions. In an 81-bed psychiatric hospital, this mixed-method study drew 7 years of incident reports and caregivers' perceptions gathered through focus groups. Incident reports on physical safety were analyzed based on the five levels of safety framework ( N = 1,316). Focus groups ( n = 9) explored the caregivers' viewpoints on patient safety and five categories of spaces. Overall findings support the five levels of safety pattern, confirming that most incidents occurred in patient rooms and bathrooms; moreover, relatively fewer incidents happened in dayrooms and corridors. Elopements are higher in hallways and dayrooms. Suicide is most common in patient rooms and bathrooms, and violence is more frequent in dayrooms. Focus groups results yielded insightful recommendations. Levels of safety framework can be adapted to seven categories where seclusion room and admission area would be two of the spaces with least incidents.

The purpose of this study was to test a model where body-related self-conscious emotions of shame, guilt, and pride were associated with physical activity regulations and behavior. Adult women (N = 389; M age = 29.82, SD = 15.20 years) completed a questionnaire assessing body-related pride, shame, and guilt, motivational regulations, and leisure-time physical activity. The hypothesized measurement and structural models were deemed adequate, as was a revised model examining shame-free guilt and guilt-free shame. In the revised structural model, body-related pride was positively significantly related to identified and intrinsic regulations. Body-related shame-free guilt was significantly associated with external, introjected, and identified regulations. Body-related guilt-free shame was significantly positively related to external and introjected regulation, and negatively associated with intrinsic regulation. Identified and intrinsic regulations were significantly positively related to physical activity (R2 = .62). These findings highlight the importance of targeting and understanding the realm of body-related self-conscious emotions and the associated links to regulations and physical activity behavior.

Brief structured physical activity in the classroom is effective for increasing student physical activity. The present study investigated the association between implementation-related contextual factors and intervention implementation after adoption of a structured classroom physical activity intervention. Six elementary-school districts adopted structured classroom physical activity programs in 2013-2014. Implementation contextual factors and intervention implementation (structured physical activity provided in past week or month, yes/no) were assessed using surveys of 337 classroom teachers from 24 schools. Mixed-effects models accounted for the nested design. Availability of resources (yes/no, ORs = 1.91-2.93) and implementation climate z-scores (ORs = 1.36-1.47) were consistently associated with implementation. Teacher-perceived classroom behavior benefits (OR = 1.29) but not student enjoyment or health benefits, and time (OR = 2.32) and academic (OR = 1.63) barriers but not student cooperation barriers were associated with implementation (all z-scores). Four implementation contextual factor composites had an additive association with implementation (OR = 1.64 for each additional favorable composite). Training and technical assistance alone may not support a large proportion of teachers to implement structured classroom physical activity. In addition to lack of time and interference with academic lessons, school climate related to whether administrators and other teachers were supportive of the intervention were key factors explaining whether teachers implemented the intervention. Evidence-based implementation strategies are needed for effectively communicating the benefits of classroom physical activity on student behavior and improving teacher and administrator climate/attitudes around classroom physical activity.

Physical activity and telomere biology: exploring the link with aging-related disease prevention.

PubMed

Ludlow, Andrew T; Roth, Stephen M

2011-02-21

Physical activity is associated with reduced risk of several age-related diseases as well as with increased longevity in both rodents and humans. Though these associations are well established, evidence of the molecular and cellular factors associated with reduced disease risk and increased longevity resulting from physical activity is sparse. A long-standing hypothesis of aging is the telomere hypothesis: as a cell divides, telomeres shorten resulting eventually in replicative senescence and an aged phenotype. Several reports have recently associated telomeres and telomere-related proteins to diseases associated with physical inactivity and aging including cardiovascular disease, insulin resistance, and hypertension. Interestingly several reports have also shown that longer telomeres are associated with higher physical activity levels, indicating a potential mechanistic link between physical activity, reduced age-related disease risk, and longevity. The primary purpose of this review is to discuss the potential importance of physical activity in telomere biology in the context of inactivity- and age-related diseases. A secondary purpose is to explore potential mechanisms and important avenues for future research in the field of telomeres and diseases associated with physical inactivity and aging.

This article describes the results of the Interventions to Safeguard Safety breakout session of the 2011 Academic Emergency Medicine (AEM) consensus conference entitled “Interventions to Assure Quality in the Crowded Emergency Department.” Using a multistep nominal group technique, experts in emergency department (ED) crowding, patient safety, and systems engineering defined knowledge gaps and priority research questions related to the maintenance of safety in the crowded ED. Consensus was reached for seven research priorities related to interventions to maintain safety in the setting of a crowded ED. Included among these are: 1) How do routine corrective processes and compensating mechanism change during crowding? 2) What metrics should be used to determine ED safety? 3) How can checklists ensure safer care and what factors contribute to their success or failure? 4) What constitutes safe staffing levels / ratios? 5) How can we align emergency medicine (EM)-specific patient safety issues with national patient safety issues? 6) How can we develop metrics and skills to recognize when an ED is getting close to catastrophic overload conditions? and 7) What can EM learn from experts and modeling from fields outside of medicine to develop innovative solutions? These priorities have the potential to inform future clinical and human factors research and extramural funding decisions related to this important topic. PMID:22168192

Commercial grade item (CGI) dedication of MDR relays for nuclear safety related applications

MDR relays manufactured by Potter and Brumfield (P and B) have been used in various safety related applications in commercial nuclear power plants. These include emergency safety features (ESF) actuation systems, emergency core cooling systems (ECCS) actuation, and reactor protection systems. The MDR relays manufactured prior to May 1990 showed signs of generic failure due to corrosion and outgassing of coil varnish. P and B has made design changes to correct these problems in relays manufactured after May 1990. However, P and B does not manufacture the relays under any 10CFR50 Appendix B quality assurance (QA) program. They manufacture themore » relays under their commercial QA program and supply these as commercial grade items. This necessitates CGI Dedication of these relays for use in nuclear-safety-related applications. This paper presents a CGI dedication program that has been used to dedicate the MDR relays manufactured after May 1990. The program is in compliance with current Nuclear Regulatory Commission (NRC) and Electric Power Research Institute (EPRI) guidelines and applicable industry standards; it specifies the critical characteristics of the relays, provides the tests and analysis required to verify the critical characteristics, the acceptance criteria for the test results, performs source verification to qualify P and B for its control of the critical characteristics, and provides documentation. The program provides reasonable assurance that the new MDR relays will perform their intended safety functions.« less

This report summarizes the findings from a review of published documents dealing with research on the environmental qualification of safety-related electric cables used in nuclear power plants. Simulations of accelerated aging and accident conditions are important considerations in qualifying the cables. Significant research in these two areas has been performed in the US and abroad. The results from studies in France, Germany, and Japan are described in this report. In recent years, the development of methods to monitor the condition of cables has received special attention. Tests involving chemical and physical examination of cable`s insulation and jacket materials, and electricalmore » measurements of the insulation properties of cables are discussed. Although there have been significant advances in many areas, there is no single method which can provide the necessary information about the condition of a cable currently in service. However, it is possible that further research may identify a combination of several methods that can adequately characterize the cable`s condition.« less

Use of the bootstrap method to develop a physical fitness test for public safety officers who serve as both police officers and firefighters

Physical fitness testing is a common tool for motivating employees with strenuous occupations to reach and maintain a minimum level of fitness. Nevertheless, the use of such tests can be hampered by several factors, including required compliance with US antidiscrimination laws. The Highland Park (Texas) Department of Public Safety implemented testing in 1991, but no single test adequately evaluated its sworn employees, who are cross-trained and serve as police officers and firefighters. In 2010, the department's fitness experts worked with exercise physiologists from Baylor Heart and Vascular Hospital to develop and evaluate a single test that would be equitable regardless of race/ethnicity, disability, sex, or age >50 years. The new test comprised a series of exercises to assess overall fitness, followed by two sequences of job-specific tasks related to firefighting and police work, respectively. The study group of 50 public safety officers took the test; raw data (e.g., the number of repetitions performed or the time required to complete a task) were collected during three quarterly testing sessions. The statistical bootstrap method was then used to determine the levels of performance that would correlate with 0, 1, 2, or 3 points for each task. A sensitivity analysis was done to determine the overall minimum passing score of 17 points. The new physical fitness test and scoring system have been incorporated into the department's policies and procedures as part of the town's overall employee fitness program. PMID:24982558

In hot weather, thermal heat generated by the body, combined with environmental heat from the sun, can lead outdoor workers to experience heat-related stress, severe illness, or even death. The aims of this study were to estimate the prevalence of heat-related symptoms and potential risk factors associated with sun safety-related behavior among Latino farmworkers. Data from interviewer-administered questionnaires were collected from a cross-sectional survey among farmworkers (N = 158) from August to September 2013. Data analysis assessed associations between work activities, sun safety behavior, and the prevalence of heat-related illness (HRI) symptoms among workers. Nearly two thirds (72%) of farmworkers experienced at least one HRI symptom and lacked proper cooling methods when working outdoors. Most workers reported wearing long-sleeved shirts (85%), long pants (98%), and baseball caps (93%). The prevalence of having one HRI symptom was 72% and 27% among workers having three or more HRI symptoms. The majority of farmworkers experience symptoms of HRI and are not provided with proper shade protection when working outdoors. Increased emphasis on administrative controls, particularly educating field supervisors and workers on how to avoid and recognize HRI, should be a priority.

High standards of quality and patient safety in hospital wards cannot be achieved without the active role of the nursing leaders that manage these units. Previous studies tended to focus on the leadership behaviours of nurses in relation to staff job satisfaction and other organizational outcomes. Less is known about the leadership skills of senior charge nurses that are effective for ensuring safety for patients and staff in their wards. The aim of the two studies was to identify the leadership behaviours of senior charge nurses that are (a) typically used and, (b) that relate to safety outcomes. In study one, semi-structured interviews were conducted with 15 senior charge nurses at an acute NHS hospital. Transcribed interviews were coded using Yukl's Managerial Practices Survey (MPS) framework. In study two, self ratings of leadership (using the MPS) from 15 senior charge nurses (SCN) and upward ratings from 82 staff nurses reporting to them were used to investigate associations between SCNs' leadership behaviours and worker and patient-related safety outcomes. The interviews in study one demonstrated the relevance of the MPS leadership framework for nurses at hospital ward level. The SCNs mainly engaged in relations-oriented (n=370, 49%), and task-oriented (n=342, 45%) behaviours, with fewer change-oriented (n=25, 3%), and lead by example behaviours (n=26, 3%). In demanding situations, more task-oriented behaviours were reported. In study two, staff nurses' ratings of their SCNs' behaviours (Monitoring and Recognizing) were related to staff compliance with rules and patient injuries (medium severity), while the self ratings of SCNs indicated that Supporting behaviours were linked to lower infection rates and Envisioning change behaviours were linked to lower infection and other safety indicators for both patients and staff. This study provides preliminary data on the usability of a standard leadership taxonomy (Yukl et al., 2002), and the related MPS

To investigate the relations between sedentary behaviors and health-related physical fitness and physical activity in middle school boys and girls. Students (n = 1515) in grades 6-8 completed the Youth Risk Behavior Survey sedentary behavior questions, the FITNESSGRAM physical fitness items, and FITNESSGRAM physical activity self-report questions. When students reported ≤ 2 hours per day of sedentary behaviors, their odds of achieving the FITNESSGRAM Healthy Fitness Zone for aerobic capacity, muscular strength and endurance, flexibility, and body composition increased. Similarly, the odds of achieving physical activity guidelines for children increased when students reported ≤ 2 hours per day of sedentary behaviors. Results illustrate the importance of keeping sedentary behaviors to ≤ 2 hours per day in middle school children, thus increasing the odds that the student will achieve sufficient health-related fitness benefits and be more likely to achieve the national physical activity guidelines.

This study compared nursing staff perceptions of safety climate in clinical units characterized by high and low ratings of leader-member exchange (LMX) and explored characteristics that might account for differences. Frontline nursing leaders' actions are critical to ensure patient safety. Specific leadership behaviors to achieve this goal are underexamined. The LMX perspective has shown promise in nonhealthcare settings as a means to explain safety climate perceptions. Cross-sectional survey of staff (n = 711) and unit directors from 34 inpatient units in an academic medical center was conducted. Significant differences were found between high and low LMX scoring units on supervisor safety expectations, organizational learning-continuous improvement, total communication, feedback and communication about errors, and nonpunitive response to errors. The LMX perspective can be used to identify differences in perceptions of safety climate among nursing staff. Future studies are needed to identify strategies to improve staff safety attitudes and behaviors. Copyright © 2011 Wolters Kluwer Health | Lippincott Williams & Wilkins

Background: Physical disability is common though not inevitable in older age and has direct bearing on a person’s ability to perform activities essential for self-care and independent living. Air pollution appears to increase the risk of several chronic diseases that contribute to the progression of disability. Objective: We evaluated long-term exposure to traffic-related air pollution (TRAP) in relation to progression in physical disability. Methods: We conducted our investigation within the Chicago Health and Aging Project. We measured participants’ exposures to TRAP using two surrogates: residential proximity to major roads (1993 onwards) and ambient concentrations of oxides of nitrogen (NOX; 1999 onwards), predicted via a geographic information systems-based spatiotemporal smoothing model (cross-validation R2 = 0.87) that incorporated community-based monitoring and resolved intraurban exposure gradients at a spatial scale of tens of meters. Participants’ lower-extremity physical ability was assessed every 3 years (1993–2012) via tandem stand, chair stand, and timed walking speed. Results: In multivariable-adjusted analyses (n = 5,708), higher long-term NOX exposure was associated with significantly faster progression in disability. Compared with the 5-year decline in physical ability score among participants in the lowest quartile of NOX exposure, decline among those in the highest exposure quartile was 1.14 units greater (95% confidence interval [CI]: –1.86, –0.42), equivalent to 3 additional years of decline among those in the lowest exposure quartile. The association was linear across the continuum of NOX exposure: per 10-ppb increment in exposure, the 5-year decline in physical ability score was 0.87 unit greater (95% CI: –1.35, –0.39). Proximity to a major road was not associated with disability progression (n = 9,994). Conclusions: These data join a growing body of evidence suggesting that TRAP exposures may accelerate aging-related

Objectives To estimate the prevalence of occupation-, transportation- and leisure-related physical activity, its compliance with recommendations, and to explore its association with demographic and socioeconomic variables in men and women of the Department of Santander (Colombia). Methods The sample consisted of 2421 people between 15 and 64 years of age, participants in the Risk Factors for Chronic Diseases of Santander cross-sectional study, developed in 2010. The Global Physical Activity Questionnaire was used for data collection. Age-adjusted prevalence ratios were calculated and multivariate analysis models were built by sex using robust Poisson regression. Results The prevalence of occupational and leisure physical activity and compliance with recommendations were lower in women. Sexual division of labor and a low socioeconomic level negatively influenced physical activity in women, limiting the possibility of practice of those principally engaged in unpaid work at home. Young or single men and those living in higher socioeconomic areas were more likely to practice physical activity in leisure time and meet recommendations. Conclusion Physical activity surveillance and related public policies should take into account the inequalities between the practice of men and women related to their socioeconomic conditions and the sexual division of labor.

Anderson, Melissa L; Najavits, Lisa M

2014-08-01

This secondary analysis investigated the impact of 12 sessions of Seeking Safety (SS) on reducing posttraumatic stress disorder (PTSD) symptoms in a sample of dually diagnosed women with physical disabilities versus nondisabled (ND) women. SS is an evidence-based and widely implemented manualized therapy for PTSD and/or substance use disorder. It is a present-focused model that promotes coping skills and psychoeducation. As part of the National Institute on Drug Abuse Clinical Trials Network (NIDA CTN), 353 participants with current PTSD and substance use disorder (SUD) were randomly assigned to partial-dose SS or Women's Health Education (WHE) group therapy conducted in community-based substance abuse treatment programs. The women were categorized as participants with disabilities (PWD; n = 20) or ND (n = 333) based on the question, "Do you receive a pension for a physical disability?" PTSD was assessed on the Clinician-Administered PTSD Scale (CAPS) at baseline and follow-ups after treatment (1 week, 3 months, 6 months, and 12 months). PWD experienced sustained reductions in PTSD symptoms when treated with SS but not WHE. Indeed, PTSD symptoms of PWD in WHE returned to baseline levels of severity by 12-month follow-up. This pattern of results was not observed among ND women, who sustained improvements on PTSD in both treatment conditions. These results suggest strong potential for using SS to treat PTSD among women with physical disabilities, and speak to the genuine need to address trauma and PTSD more directly with PWD. Our results are also consistent with other findings from the NIDA CTN trial, in which virtually all significant results evidenced SS outperforming WHE.

OBJECTIVE: To describe the long-term productivity costs of occupational assaults. DATA SOURCES/STUDY SETTING: All incidents of physical assaults that resulted in indemnity payments, identified from the Minnesota Department of Labor and Industry (DLI) Workers' Compensation system in 1992. Medical expenditures were obtained from insurers, and data on lost wages, legal fees, and permanency ratings were collected from DLI records. Insurance administrative expenses were estimated. Lost fringe benefits and household production losses were imputed. STUDY DESIGN: The human capital approach was used to describe the long-term costs of occupational assaults. Economic software was used to apply a modified version of Rice, MacKenzie, and Associates' (1989) model for estimating the present value of past losses from 1992 through 1995 for all cases, and the future losses for cases open in 1996. PRINCIPAL FINDINGS: The total costs for 344 nonfatal work-related assaults were estimated at $5,885,448 (1996 dollars). Calculation of injury incidence and average costs per case and per employee identified populations with an elevated risk of assault. An analysis by industry revealed an elevated risk for workers employed in justice and safety (incidence: 198/100,000; $19,251 per case; $38 per employee), social service (incidence: 127/100,000; $24,210 per case; $31 per employee), and health care (incidence: 76/100,000; $13,197 per case; $10 per employee). CONCLUSIONS: Identified subgroups warrant attention for risk factor identification and prevention efforts. Cost estimates can serve as the basis for business calculations on the potential value of risk management interventions. PMID:10966089

Perceived Neighborhood Safety, Social Cohesion, and Psychological Health of Older Adults.

We aimed to investigate the interactive effects of perceived neighborhood safety and social cohesion on the psychological health of older adults with and without functional impairments. This cross-sectional study included 13,897 community-dwelling older adults (aged 65 years and older) from the 2011-2012 California Health Interview Survey (CHIS). Hypotheses were tested using weighted moderated ordinary least squared regression analysis. Perceived neighborhood safety was significantly associated with psychological health regardless of respondents' physical functioning, although the effect was greater among older adults with functional limitations. Perceived social cohesion, however, was only significantly related to psychological health among those with functional limitations. Among physically impaired respondents, social cohesion buffered the ill-effect of an unsafe neighborhood on psychological health. Findings suggest that efforts to promote perceived neighborhood safety and social cohesion are essential to the well-being of older adults. Special attention should be paid to older adults with functional limitations, who appear to be more vulnerable to the negative effects of neighborhood environments.

This study was designed to evaluate the effects of safety and health training on work-related injury in the construction industry. Union health insurance records, union training records, and workers compensation data for 1993 and 1994 were analyzed for more than 8000 construction laborers in Washington State. After controlling for demographic factors, laborers who received safety and health training during the study period were 12% (95% confidence interval [CI] = 0.75-1.02) less likely than nontrained laborers to file for workers compensation. Among workers 16 to 24 years old, training was associated with a 42% (95% CI = 0.35-0.95) reduction in claims. These findings provide evidence of the effectiveness of safety and health training in preventing occupational injuries among construction laborers, particularly among younger workers. However, the results cover only a limited time and the long-term effects remain unclear.

2014-10-01

Working environments that are both civil and safe are good for business and employee well-being. Civility has been empirically linked to such important outcomes as organizational performance and individuals' positive work-related attitudes, yet research relating civility to safety is lacking. In this study, we link perceptions of civility norms to perceptions of safety climate and safety outcomes. Drawing on social exchange theory, we proposed and tested a model in 2 samples wherein civility norms indirectly relate to safety outcomes through associations with various safety climate facets. Our results supported direct relationships between civility and management safety climate and coworker safety climate. Additionally, indirect effects of civility norms on unsafe behaviors and injuries were observed. Indirect effects of civility norms on unsafe behaviors were observed through coworker safety climate and work-safety tension. Indirect effects of civility norms on injuries were observed through management safety climate and work-safety tension for full-time employees, although these effects did not hold for part-time employees. This study provides initial evidence that researchers and practitioners may want to look beyond safety climate to civility norms to more comprehensively understand the origins of unsafe behaviors and injuries and to develop appropriate preventive interventions.

Objective To compare the rates of physical, psychiatric, and suicide-related events in adolescents with MDD treated with fluoxetine alone (FLX), cognitive-behavioral therapy (CBT), combination treatment (COMB), or placebo (PBO). Method Safety assessments included adverse events (AEs) collected by spontaneous report, as well as systematic measures for specific physical and psychiatric symptoms. Suicidal ideation and suicidal behavior were systematically assessed by self- and clinician reports. Suicidal events were also reanalyzed by the Columbia Group and expert raters using the Columbia-Classification Algorithm for Suicidal Assessment used in the U.S. Food and Drug Administration reclassification effort. Results Depressed adolescents reported high rates of physical symptoms at baseline, which improved as depression improved. Sedation, insomnia, vomiting, and upper abdominal pain occurred in at least 2% of those treated with FLX and/or COMB and at twice the rate of placebo. The rate of psychiatric AEs was 11% in FLX, 5.6% in COMB, 4.5% in PBO, and 0.9% in CBT. Suicidal ideation improved overall, with greatest improvement in COMB. Twenty-four suicide-related events occurred during the 12-week period: 5 patients (4.7%) in COMB, 10 (9.2%) in FLX, 5 (4.5%) in CBT, and 3 (2.7%) in placebo. Statistically, only FLX had more suicide-related events than PBO (p = .0402, odds ratio [OR] = 3.7, 95% CI 1.00–13.7). Only five actual attempts occurred (2 COMB, 2 FLX, 1 CBT, 0 PBO). There were no suicide completions. Conclusions Different methods for eliciting AEs produce different results. In general, as depression improves, physical complaints and suicidal ideation decrease in proportion to treatment benefit. In this study, psychiatric AEs and suicide-related events are more common in FLX-treated patients. COMB treatment may offer a more favorable safety profile than medication alone in adolescent depression. PMID:17135989

Evidence for consciousness-related anomalies in random physical systems

Speculations about the role of consciousness in physical systems are frequently observed in the literature concerned with the interpretation of quantum mechanics. While only three experimental investigations can be found on this topic in physics journals, more than 800 relevant experiments have been reported in the literature of parapsychology. A well-defined body of empirical evidence from this domain was reviewed using meta-analytic techniques to assess methodological quality and overall effect size. Results showed effects conforming to chance expectation in control conditions and unequivocal non-chance effects in experimental conditions. This quantitative literature review agrees with the findings of two earlier reviews, suggesting the existence of some form of consciousness-related anomaly in random physical systems.

Concerns related to Safety Management of Engineered Nanomaterials in research environment

NASA Astrophysics Data System (ADS)

Groso, A.; Meyer, Th

2013-04-01

Since the rise of occupational safety and health research on nanomaterials a lot of progress has been made in generating health effects and exposure data. However, when detailed quantitative risk analysis is in question, more research is needed, especially quantitative measures of workers exposure and standards to categorize toxicity/hazardousness data. In the absence of dose-response relationships and quantitative exposure measurements, control banding (CB) has been widely adopted by OHS community as a pragmatic tool in implementing a risk management strategy based on a precautionary approach. Being in charge of health and safety in a Swiss university, where nanomaterials are largely used and produced, we are also faced with the challenge related to nanomaterials' occupational safety. In this work, we discuss the field application of an in-house risk management methodology similar to CB as well as some other methodologies. The challenges and issues related to the process will be discussed. Since exact data on nanomaterials hazardousness are missing for most of the situations, we deduce that the outcome of the analysis for a particular process is essentially the same with a simple methodology that determines only exposure potential and the one taking into account the hazardousness of ENPs. It is evident that when reliable data on hazardousness factors (as surface chemistry, solubility, carcinogenicity, toxicity etc.) will be available, more differentiation will be possible in determining the risk for different materials. On the protective measures side, all CB methodologies are inclined to overprotection side, only that some of them suggest comprehensive protective/preventive measures and others remain with basic advices. The implementation and control of protective measures in research environment will also be discussed.

Fatigue and work safety behavior in men during early fatherhood.

PubMed

Mellor, Gary; St John, Winsome

2012-01-01

This study investigated the relationship between fatigue and work safety behavior of fathers with new babies. A total of 241 fathers completed a questionnaire at 6 and 12 weeks postpartum with items on fatigue and safety behavior at work. Results revealed that fathers worked long hours, reported a moderate-to-high physical intensity of work, and experienced interrupted sleep averaging less than 6 hours. Fathers also reported moderate fatigue at both 6 and 12 weeks postbirth, which was inversely related to safety behavior. Both fatigue and sleep history made a small but statistically significant contribution to safety behavior results at 6 and 12 weeks postbirth. Findings suggest that working fathers with babies experience fatigue during early fatherhood and are unable to recover due to interrupted and poor sleep patterns. Managers should consider the potential for fatigue to compromise work safety and develop risk management strategies that target new fathers.

What is the relation between fear of falling and physical activity in older adults?

To describe the association between fear of falling (FOF) and total daily activity in older adults. Cross-sectional observational study. Ambulatory clinical research training center. Community-dwelling older adults aged ≥64 years (N=78), who were independent in ambulation with or without an assistive device. Not applicable. FOF was defined by self-reported fear ratings using the Survey of Activities and Fear of Falling in the Elderly and self-reported fear status determined by response to the following question: Are you afraid of falling? Physical function was assessed using the Late Life Function and Disability Instrument. Physical activity was recorded using an accelerometer worn on the waist for 7 consecutive days, and mean daily counts of activity per minute were averaged over the 7-day period. Fear ratings were related to total daily activity (r=-.26, P=.02). The relation was not as strong as the relation of function and physical activity (r=.45, P<.001). When stratified by exercise status or functional status, fear was no longer related to total daily activity. Physical function explained 19% of the variance in physical activity, whereas the addition of fear status did not add to the explained variance in physical activity. FOF is related to total daily physical activity; however, FOF was not independently associated with physical activity when accounting for physical function. Some FOF may be reported as a limitation in function. Copyright © 2013 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Security Implications of Physical Design Attributes in the Emergency Department.

PubMed

Pati, Debajyoti; Pati, Sipra; Harvey, Thomas E

2016-07-01

Security, a subset of safety, is equally important in the efficient delivery of patient care. The emergency department (ED) is susceptible to violence creating concerns for the safety and security of patients, staff, and visitors and for the safe and efficient delivery of care. Although there is an implicit and growing recognition of the role of the physical environment, interventions typically have been at the microlevel. The objective of this study was to identify physical design attributes that potentially influence safety and efficiency of ED operations. An exploratory, qualitative research design was adopted to examine the efficiency and safety correlates of ED physical design attributes. The study comprised a multimeasure approach involving multidisciplinary gaming, semistructured interviews, and touring interviews of frontline staff in four EDs at three hospital systems across three states. Five macro physical design attributes (issues that need to be addressed at the design stage and expensive to rectify once built) emerged from the data as factors substantially associated with security issues. They are design issues pertaining to (a) the entry zone, (b) traffic management, (c) patient room clustering, (d) centralization versus decentralization, and (e) provisions for special populations. Data from this study suggest that ED security concerns are generally associated with three sources: (a) gang-related violence, (b) dissatisfied patients, and (c) behavioral health patients. Study data show that physical design has an important role in addressing the above-mentioned concerns. Implications for ED design are outlined in the article. © The Author(s) 2016.

Little is known about how neighborhood crime may relate to health in diabetes patients. We examined associations between individuals' perceptions of neighborhood safety or violent crime and stress, physical activity, body mass index (BMI) or hemoglobin A1c (HbA1c) in a sample (n=721) of adults (mean age:63) with diabetes. Self-reported neighborhood safety, violent crime, physical activity, and stress were collected and linked to clinical measures of BMI and HbA1c. Approximately 54% and 15% of patients reported neighborhood safety concerns and violent crimes, respectively. Any neighborhood safety concerns (β=1.14, 95% C.I. 0.04-2.24) and violent crime (β=2.04, 95% C.I. 0.34-3.73) were associated with BMI in adjusted analysis. Any violent crime was associated with class II-III obesity (BMI≥35) (OR=1.34, 95% C.I.: 1.02, 1.75). There were no significant associations between neighborhood safety concerns or violent crime with stress, physical activity, or HbA1c. Neighborhood safety is associated with BMI and obesity. Further studies, including longitudinal designs, are needed to study how people with diabetes may be influenced by a sense of poor personal safety in their neighborhoods.

"If I had to do it, then I would": Understanding early middle school students' perceptions of physics and physics-related careers by gender

Dare, Emily A.; Roehrig, Gillian H.

2016-12-01

[This paper is part of the Focused Collection on Gender in Physics.] This study examined the perceptions of 6th grade middle school students regarding physics and physics-related careers. The overarching goal of this work was to understand similarities and differences between girls' and boys' perceptions surrounding physics and physics-related careers as part of a long-term effort to increase female interest and representation in this particular field of science. A theoretical framework based on the literature of girl-friendly and integrated STEM instructional strategies guided this work to understand how instructional strategies may influence and relate to students' perceptions. This convergent parallel mixed-methods study used a survey and focus group interviews to understand similarities and differences between girls' and boys' perceptions. Our findings indicate very few differences between girls and boys, but show that boys are more interested in the physics-related career of engineering. While girls are just as interested in science class as their male counterparts, they highly value the social aspect that often accompanies hands-on group activities. These findings shed light on how K-12 science reform efforts might help to increase the number of women pursuing careers related to physics.

Physical activity is associated with health-related quality of life (HRQL) in clinical populations, but less is known whether this relationship exists in older men and women who are healthy. Thus, this study determined if physical activity was related to HRQL in apparently healthy, older subjects. Measures were obtained from 112 male and female volunteers (70 +/- 8 years, mean +/- SD) recruited from media advertisements and flyers around the Norman, Oklahoma area. Data was collected using a medical history questionnaire, HRQL from the Medical Outcomes Survey short form-36 questionnaire, and physical activity level from the Johnson Space Center physical activity scale. Subjects were separated into either a higher physically active group (n = 62) or a lower physically active group (n = 50) according to the physical activity scale. The HRQL scores in all eight domains were significantly higher (p < 0.05) in the group reporting higher physical activity. Additionally, the more active group had fewer females (44% vs. 72%, p = 0.033), and lower prevalence of hypertension (39% vs. 60%, p = 0.041) than the low active group. After adjusting for gender and hypertension, the more active group had higher values in the following five HRQL domains: physical function (82 +/- 20 vs. 68 +/- 21, p = 0.029), role-physical (83 +/- 34 vs. 61 +/- 36, p = 0.022), bodily pain (83 +/- 22 vs. 66 +/- 23, p = 0.001), vitality (74 +/- 15 vs. 59 +/- 16, p = 0.001), and social functioning (92 +/- 18 vs. 83 +/- 19, p = 0.040). General health, role-emotional, and mental health were not significantly different (p > 0.05) between the two groups. Healthy older adults who regularly participated in physical activity of at least moderate intensity for more than one hour per week had higher HRQL measures in both physical and mental domains than those who were less physically active. Therefore, incorporating more physical activity into the lifestyles of sedentary or slightly active older individuals may

This study uses a mixed methods approach to 1) identify surrounding residents' perceived expectations for Housing Opportunities for People Everywhere (HOPE VI) policy on physical activity outcomes and to 2) quantitatively examine the odds of neighborhood-based physical activity pre-/post-HOPE VI in a low socioeconomic status, predominantly African American community in Birmingham, Alabama. To address aim one, we used group concept mapping which is a structured approach for data collection and analyses that produces pictures/maps of ideas. Fifty-eight residents developed statements about potential influences of HOPE VI on neighborhood-based physical activity. In the quantitative study, we examined whether these potential influences increased the odds of neighborhood walking/jogging. We computed block entry logistic regression models with a larger cohort of residents at baseline (n = 184) and six-months (n = 142, 77% retention; n = 120 for all informative variables). We examined perceived neighborhood disorder (perceived neighborhood disorder scale), walkability and aesthetics (Neighborhood Environment Walkability Scale) and HOPE VI-related community safety and safety for physical activity as predictors. During concept mapping, residents generated statements that clustered into three distinct concepts, "Increased Leisure Physical Activity," "Safe Play Areas," and "Generating Health Promoting Resources." The quantitative analyses indicated that changes in neighborhood walkability increased the odds of neighborhood-based physical activity (p = 0.04). When HOPE VI-related safety for physical activity was entered into the model, it was associated with increased odds of physical activity (p = 0.04). Walkability was no longer statistically significant. These results suggest that housing policies that create walkable neighborhoods and that improve perceptions of safety for physical activity may increase neighborhood-based physical activity. However, the longer

Proximity under Threat: The Role of Physical Distance in Intergroup Relations

Wohl, Michael J. A.; Van Bavel, Jay J.

2016-01-01

Throughout human history, social groups have invested immense amounts of wealth and time to keep threatening out-groups at a distance. In the current research, we explored the relationship between intergroup threat, physical distance, and discrimination. Specifically, we examined how intergroup threat alters estimates of physical distance to out-groups and how physical proximity affects intergroup relations. Previous research has found that people judge threatening out-groups as physically close. In Studies 1 and 2, we examined ways to attenuate this bias. In Study 1 a secure (vs. permeable) US-Mexico border reduced the estimated proximity to Mexico City among Americans who felt threatened by Mexican immigration. In Study 2, intergroup apologies reduced estimates of physical proximity to a threatening cross-town rival university, but only among participants with cross-group friendships. In Study 3, New York Yankees fans who received an experimental induction of physical proximity to a threatening out-group (Boston Red Sox) had a stronger relationship between their collective identification with the New York Yankees and support for discriminatory policies toward members of the out-group (Red Sox fans) as well as how far they chose to sit from out-group members (Red Sox fans). Together, these studies suggest that intergroup threat alters judgment of physical properties, which has important implications for intergroup relations. PMID:27467267

Exploring the relations among physical fitness, executive functioning, and low academic achievement.

2018-03-01

Physical fitness seems to be related to academic performance, at least when taking the role of executive functioning into account. This assumption is highly relevant for the vulnerable population of low academic achievers because their academic performance might benefit from enhanced physical fitness. The current study examined whether physical fitness and executive functioning are independent predictors of low mathematics and spelling achievement or whether the relation between physical fitness and low achievement is mediated by specific executive functions. In total, 477 students from second- and third-grade classes of 12 primary schools were classified as either low or average-to-high achievers in mathematics and spelling based on their scores on standardized achievement tests. Multilevel structural equation models were built with direct paths between physical fitness and academic achievement and added indirect paths via components of executive functioning: inhibition, verbal working memory, visuospatial working memory, and shifting. Physical fitness was only indirectly related to low achievement via specific executive functions, depending on the academic domain involved. Verbal working memory was a mediator between physical fitness and low achievement in both domains, whereas visuospatial working memory had a mediating role only in mathematics. Physical fitness interventions aiming to improve low academic achievement, thus, could potentially be successful. The mediating effect of executive functioning suggests that these improvements in academic achievement will be preceded by enhanced executive functions, either verbal working memory (in spelling) or both verbal and visuospatial working memory (in mathematics).

Here, we review liquid hydrogen (LH 2) as a maritime vessel fuel, from descriptions of its fundamental properties to its practical application and safety aspects, in the context of the San Francisco Bay Renewable Energy Electric Vessel with Zero Emissions (SF-BREEZE) high-speed fuel-cell ferry. Since marine regulations have been formulated to cover liquid natural gas (LNG) as a primary propulsion fuel, we frame our examination of LH 2 as a comparison to LNG, for both maritime use in general, and the SF-BREEZE in particular. Due to weaker attractions between molecules, LH 2 is colder than LNG, and evaporates more easily.more » We describe the consequences of these physical differences for the size and duration of spills of the two cryogenic fuels. The classical flammability ranges are reviewed, with a focus on how fuel buoyancy modifies these combustion limits. We examine the conditions for direct fuel explosion (detonation) and contrast them with initiation of normal (laminar) combustion. Direct fuel detonation is not a credible accident scenario for the SF-BREEZE. For both fuels, we review experiments and theory elucidating the deflagration to detonation transition (DDT). LH 2 fires have a shorter duration than energy-equivalent LNG fires, and produce significantly less thermal radiation. The thermal (infrared) radiation from hydrogen fires is also strongly absorbed by humidity in the air. Hydrogen permeability is not a leak issue for practical hydrogen plumbing. We describe the chemistry of hydrogen and methane at iron surfaces, clarifying their impact on steel-based hydrogen storage and transport materials. These physical, chemical and combustion properties are pulled together in a comparison of how a LH 2 or LNG pool fire on the Top Deck of the SF-BREEZE might influence the structural integrity of the aluminum deck. Neither pool fire scenario leads to net heating of the aluminum decking. Overall, LH 2 and LNG are very similar in their physical and combustion

Subjective relative deprivation is associated with poorer physical and mental health.

PubMed

Mishra, Sandeep; Carleton, R Nicholas

2015-12-01

Substantial epidemiological evidence has shown that income inequality and objective measures of relative deprivation are associated with poorer health outcomes. However, surprisingly little research has examined whether subjective feelings of relative deprivation are similarly linked with poorer health outcomes. The relative deprivation hypothesis suggests that inequality affects health at the individual level through negative consequences of social comparison. We directly examined the relationship between subjective feelings of personal relative deprivation and self-reported physical and mental health in a diverse community sample (n = 328). Results demonstrated that subjective feelings of personal relative deprivation are associated with significantly poorer physical and mental health. These relationships held even when accounting for covariates that have been previously associated with both relative deprivation and health. These results further support the link between relative deprivation and health outcomes and suggest that addressing root causes of relative deprivation may lead to greater individual health.

Safety margins in older adults increase with improved control of a dynamic object

PubMed Central

Hasson, Christopher J.; Sternad, Dagmar

2014-01-01

Older adults face decreasing motor capabilities due to pervasive neuromuscular degradations. As a consequence, errors in movement control increase. Thus, older individuals should maintain larger safety margins than younger adults. While this has been shown for object manipulation tasks, several reports on whole-body activities, such as posture and locomotion, demonstrate age-related reductions in safety margins. This is despite increased costs for control errors, such as a fall. We posit that this paradox could be explained by the dynamic challenge presented by the body or also an external object, and that age-related reductions in safety margins are in part due to a decreased ability to control dynamics. To test this conjecture we used a virtual ball-in-cup task that had challenging dynamics, yet afforded an explicit rendering of the physics and safety margin. The hypotheses were: (1) When manipulating an object with challenging dynamics, older adults have smaller safety margins than younger adults. (2) Older adults increase their safety margins with practice. Nine young and 10 healthy older adults practiced moving the virtual ball-in-cup to a target location in exactly 2 s. The accuracy and precision of the timing error quantified skill, and the ball energy relative to an escape threshold quantified the safety margin. Compared to the young adults, older adults had increased timing errors, greater variability, and decreased safety margins. With practice, both young and older adults improved their ability to control the object with decreased timing errors and variability, and increased their safety margins. These results suggest that safety margins are related to the ability to control dynamics, and may explain why in tasks with simple dynamics older adults use adequate safety margins, but in more complex tasks, safety margins may be inadequate. Further, the results indicate that task-specific training may improve safety margins in older adults. PMID:25071566

The aim of this study was to evaluate the ratio of significant weakness in the affected arm of breast cancer-related lymphedema patients to their unaffected side. Another purpose was to identify factors related to arm weakness and physical function in patients with breast cancer-related lymphedema. Consecutive patients (n = 80) attended a single evaluation session following their outpatient lymphedema clinic visit. Possible independent factors (i.e., lymphedema, pain, psychological, educational, and behavioral) were evaluated. Handgrip strength was used to assess upper extremity muscle strength and the disabilities of arm, shoulder, and hand (DASH) questionnaire was used to assess upper extremity physical function. Multivariate logistic regression was performed using factors that had significant differences between the handgrip weakness and non-weakness groups. Out of the 80 patients with breast cancer-related lymphedema, 29 patients (36.3 %) had significant weakness in the affected arm. Weakness of the arm with lymphedema was not related to lymphedema itself, but was related to the fear of using the affected limb (odds ratio = 1.76, 95 % confidence interval = 1.30-2.37). Fears of using the affected limb and depression significantly contributed to the variance in DASH scores. Appropriate physical and psychological interventions, including providing accurate information and reassurance of physical activity safety, are necessary to prevent arm weakness and physical dysfunction in patients with breast cancer-related lymphedema.

Dog ownership and health-related physical activity among Japanese adults.

Oka, Koichiro; Shibata, Ai

2009-07-01

Dog ownership appears to have associated health benefits as a result of increased physical activity through dog walking. This study examined the association between dog ownership and health-related physical activity among Japanese adults. Male and female respondents to an Internet-based cross-sectional survey were divided into the following groups: dog owner (DOG), nondog pet owner (NDOG), and nonpet owner (NPOG). Moderate and vigorous physical activity amount (MVPA), walking amount (Walking), and sedentary behavior time (SB) were estimated from the International Physical Activity Questionnaire. Analyses of covariance and logistic regression analysis were used. The differences in MVPA, Walking, and SB were statistically significant among the three groups. DOG had a significantly greater amount of MVPA than NDOG and NPOG. DOG also had a significantly greater amount of Walking and less SB time than NPOG, and DOG was 1.5 times more likely to meet the physical activity recommendation than NDOG and NPOG. The dog owners had higher physical activity levels than owners of other kinds of pets and those without any pets, suggesting that dogs may play a major role in promoting physical activity. However, only 30% of the dog owners met the recommended criteria for physical activity.

To assess the effects of exercise intervention on nurses' health-related physical fitness. Regular exercise that includes gymnastics or aerobics has a positive effect on fitness. In Taiwan, there are not much data which assess the effects of exercise intervention on nurses' health-related physical fitness. Many studies have reported the high incidence of musculoskeletal disorders (MSDs) in nurses However, there has been limited research on intervention programs that are designed to improve the general physical fitness of nurses. A quasi-experimental study was conducted at a medical centre in central Taiwan. Ninety nurses from five different units of a hospital volunteered to participate in this study and participated in an experimental group and a control group. The experimental group engaged in a three-month intervention program consisting of treadmill exercise. Indicators of the health-related physical fitness of both groups were established and assessed before and after the intervention. Before intervention, the control group had significantly better grasp strength, flexibility and durability of abdominal muscles than the experimental group (p < 0.05). After the intervention, logistic regression was used to adjust for marital status, work duration, regular exercise and workload and found that the experimental group performed significantly better (p < 0.05) on body mass index, grasp strength, flexibility, durability of abdominal and back muscles and cardiopulmonary function. This study demonstrates that the development and implementation of an intervention program can promote and improve the health-related physical fitness of nurses. It is suggested that nurses engage in an exercise program while in the workplace to lower the risk of MSDs and to promote working efficiency.

Relative Physical Position as an Impression-Management Strategy: Sex Differences in Its Use and Implications.

PubMed

Makhanova, Anastasia; McNulty, James K; Maner, Jon K

2017-05-01

People's physical position relative to others may shape how those others perceive them. The research described here suggests that people use relative physical position to manage impressions by strategically positioning themselves either higher or lower relative to ostensible observers. Five studies supported the prediction that women take and display photographs portraying themselves in a low relative physical position to highlight their youthful features and appear attractive, whereas men take and display photographs portraying themselves in a high relative physical position to highlight their size and appear dominant. The effectiveness of these strategies was confirmed in two studies that measured social perceptions of male and female targets who varied in their relative position. In sum, as do members of other social species, people use relative physical position to manage social impressions, and although these impression-management strategies may have deep ancestral roots, they appear to manifest themselves through a contemporary human modality-photographs.

Absolute versus relative intensity of physical activity in a dose-response context.

Shephard, R J

2001-06-01

To examine the importance of relative versus absolute intensities of physical activity in the context of population health. A standard computer-search of the literature was supplemented by review of extensive personal files. Consensus reports (Category D Evidence) have commonly recommended moderate rather than hard physical activity in the context of population health. Much of the available literature provides Category C Evidence. It has often confounded issues of relative intensity with absolute intensity or total weekly dose of exercise. In terms of cardiovascular health, there is some evidence for a threshold intensity of effort, perhaps as high as 6 METs, in addition to a minimum volume of physical activity. Decreases in blood pressure and prevention of stroke seem best achieved by moderate rather than high relative intensities of physical activity. Many aspects of metabolic health depend on the total volume of activity; moderate relative intensities of effort are more effective in mobilizing body fat, but harder relative intensities may help to increase energy expenditures postexercise. Hard relative intensities seem needed to augment bone density, but this may reflect an associated increase in volume of activity. Hard relative intensities of exercise induce a transient immunosuppression. The optimal intensity of effort, relative or absolute, for protection against various types of cancer remains unresolved. Acute effects of exercise on mood state also require further study; long-term benefits seem associated with a moderate rather than a hard relative intensity of effort. The importance of relative versus absolute intensity of effort depends on the desired health outcome, and many issues remain to be resolved. Progress will depend on more precise epidemiological methods of assessing energy expenditures and studies that equate total energy expenditures between differing relative intensities. There is a need to focus on gains in quality-adjusted life expectancy.

The Role of Interpersonal Relations in Healthcare Team Communication and Patient Safety: A Proposed Model of Interpersonal Process in Teamwork.

PubMed

Lee, Charlotte Tsz-Sum; Doran, Diane Marie

2017-06-01

Patient safety is compromised by medical errors and adverse events related to miscommunications among healthcare providers. Communication among healthcare providers is affected by human factors, such as interpersonal relations. Yet, discussions of interpersonal relations and communication are lacking in healthcare team literature. This paper proposes a theoretical framework that explains how interpersonal relations among healthcare team members affect communication and team performance, such as patient safety. We synthesized studies from health and social science disciplines to construct a theoretical framework that explicates the links among these constructs. From our synthesis, we identified two relevant theories: framework on interpersonal processes based on social relation model and the theory of relational coordination. The former involves three steps: perception, evaluation, and feedback; and the latter captures relational communicative behavior. We propose that manifestations of provider relations are embedded in the third step of the framework on interpersonal processes: feedback. Thus, varying team-member relationships lead to varying collaborative behavior, which affects patient-safety outcomes via a change in team communication. The proposed framework offers new perspectives for understanding how workplace relations affect healthcare team performance. The framework can be used by nurses, administrators, and educators to improve patient safety, team communication, or to resolve conflicts.

Recent studies have suggested that the cerebellum contributes to the central processing of pain, including pain-related learning and memory processes. As a complex experience with multiple emotional and cognitive facets, the response to pain and its underlying neural correlates differ between men and women. However, it remains poorly understood whether and to what extent sex differences exist in the cerebellar contribution to pain-related associative learning processes. In the present conditioning study with experimental abdominal pain as unconditioned stimuli (US), we assessed sex-dependent differences in behavioral and neural responses to conditioned warning and safety cues in healthy volunteers. The results revealed that in response to visual stimuli signaling safety from abdominal pain (CS(-)), women showed enhanced cerebellar activation in lobules I-IV, V, VI, VIIIa, IX and X as well as Crus II and the dentate nucleus, which are mostly representative of somatomotor networks. On the other hand, men showed enhanced neural activation in lobules I-IV, VI, VIIb, VIIIb, IX as well as Crus I and II in response to CS(-), which are representative of frontoparietal and ventral attention networks. No sex differences were observed in response to pain-predictive warning signals (CS(+)). Similarly, men and women did not differ in behavioral measures of conditioning, including conditioned changes in CS valence and contingency awareness. Together, we could demonstrate that the cerebellum is involved in associative learning processes of conditioned anticipatory safety from pain and mediates sex differences in the underlying neural processes. Given the high prevalence of chronic pain conditions in women, these results may contribute to improve our understanding of the acquisition and manifestation of chronic abdominal pain syndromes.

Integrating Safety Assessment Methods using the Risk Informed Safety Margins Characterization (RISMC) Approach

DOE Office of Scientific and Technical Information (OSTI.GOV)

Curtis Smith; Diego Mandelli

Safety is central to the design, licensing, operation, and economics of nuclear power plants (NPPs). As the current light water reactor (LWR) NPPs age beyond 60 years, there are possibilities for increased frequency of systems, structures, and components (SSC) degradations or failures that initiate safety significant events, reduce existing accident mitigation capabilities, or create new failure modes. Plant designers commonly “over-design” portions of NPPs and provide robustness in the form of redundant and diverse engineered safety features to ensure that, even in the case of well-beyond design basis scenarios, public health and safety will be protected with a very highmore » degree of assurance. This form of defense-in-depth is a reasoned response to uncertainties and is often referred to generically as “safety margin.” Historically, specific safety margin provisions have been formulated primarily based on engineering judgment backed by a set of conservative engineering calculations. The ability to better characterize and quantify safety margin is important to improved decision making about LWR design, operation, and plant life extension. A systematic approach to characterization of safety margins and the subsequent margin management options represents a vital input to the licensee and regulatory analysis and decision making that will be involved. In addition, as research and development (R&D) in the LWR Sustainability (LWRS) Program and other collaborative efforts yield new data, sensors, and improved scientific understanding of physical processes that govern the aging and degradation of plant SSCs needs and opportunities to better optimize plant safety and performance will become known. To support decision making related to economics, readability, and safety, the RISMC Pathway provides methods and tools that enable mitigation options known as margins management strategies. The purpose of the RISMC Pathway R&D is to support plant decisions for risk

Background Light physical activity is known to reduce atrial fibrillation risk, whereas moderate to vigorous physical activity may result in an increased risk. However, the question of what volume of physical activity can be considered beneficial remains poorly understood. The scope of the present work was to examine the relation between physical activity volume and atrial fibrillation risk. Design A comprehensive systematic review was performed following the PRISMA guidelines. Methods A non-linear meta-regression considering the amount of energy spent in physical activity was carried out. The first derivative of the non-linear relation between physical activity and atrial fibrillation risk was evaluated to determine the volume of physical activity that carried the minimum atrial fibrillation risk. Results The dose-response analysis of the relation between physical activity and atrial fibrillation risk showed that physical activity at volumes of 5-20 metabolic equivalents per week (MET-h/week) was associated with significant reduction in atrial fibrillation risk (relative risk for 19 MET-h/week = 0.92 (0.87, 0.98). By comparison, physical activity volumes exceeding 20 MET-h/week were unrelated to atrial fibrillation risk (relative risk for 21 MET-h/week = 0.95 (0.88, 1.02). Conclusion These data show a J-shaped relation between physical activity volume and atrial fibrillation risk. Physical activity at volumes of up to 20 MET-h/week is associated with reduced atrial fibrillation risk, whereas volumes exceeding 20 MET-h/week show no relation with risk.

This study was aimed at analysing the association between socioeconomic indicators and adolescents' physical activity and health-related fitness. The study involved 716 adolescents from both genders whose age ranged from 10 to 18 years-old (46.8% male) who answered a questionnaire for estimating their habitual physical activity, socioeconomic status; two health-related physical fitness tests were also performed. The socioeconomic indicators analysed concerned their parents' educational level and the number of bathrooms, TVs, cars, housemaids, refrigerators and freezers in their homes. A positive association was found between paternal education (PR=1.61 (range 1.27-2.10) and 1.41 (1.10-1.83)) and housemaids (PR=1.97 (1.04-3.81) and 1.92 (1.05-3.52)) with recommended physical activity and leisure time physical activity, respectively. The number of cars (PR=1.48: 1.02-2.19) and freezers (PR=1.88: 1.12-3.18) was positively associated with leisure time physical activity and the number of TVs negatively so (PR=0.75: 0.63-0.89). The number of TVs (PR=0.80: 0.67-0.96) and cars (PR=0.70: 0.55-0.89) was negatively associated with cardiorespiratory fitness whilst paternal education (PR=1.17: 1.00-1.37) and the number of bathrooms in the home (PR=1.25: 1.02-1.54) were positively associated with muscular strength. Physical activity and health-related physical fitness were associated with socioeconomic status. However, such association depended on the socioeconomic indicator being analysed. Caution should be taken when analysing studies which use different socioeconomic indicators.

Activity levels are known to decline with age and there is growing evidence of associations between the school environment and physical activity. In this study we investigated how objectively measured one-year changes in physical activity may be associated with school-related factors in 9- to 10-year-old British children. Data were analysed from 839 children attending 89 schools in the SPEEDY (Sport, Physical Activity, and Eating behaviours: Environmental Determinants in Young People) study. Outcomes variables were one year changes in objectively measured sedentary, moderate, and vigorous physical activity, with baseline measures taken when the children were 9-10 years old. School characteristics hypothesised to be associated with change in physical activity were identified from questionnaires, grounds audits, and computer mapping. Associations were examined using simple and multivariable multilevel regression models for both school (9 am - 3 pm) and travel (8-9 am and 3-4 pm) time. Significant associations during school time included the length of the morning break which was found to be supportive of moderate (β coefficient: 0.68 [p: 0.003]) and vigorous (β coefficient: 0.52 [p: 0.002]) activities and helps to prevent adverse changes in sedentary time (β coefficient: -2.52 [p: 0.001]). During travel time, positive associations were found between the presence of safe places to cross roads around the school and changes in moderate (β coefficient: 0.83 [p:0.022]) and vigorous (β coefficient: 0.56 [p:0.001]) activity, as well as sedentary time (β coefficient: -1.61 [p:0.005]). This study suggests that having longer morning school breaks and providing road safety features such as cycling infrastructure, a crossing guard, and safe places for children to cross the road may have a role to play in supporting the maintenance of moderate and vigorous activity behaviours, and preventing the development of sedentary behaviours in children.

Magnuson, Bernadene A; Jonaitis, Tomas S; Card, Jeffrey W

2011-08-01

Nanotechnology and nanomaterials have tremendous potential to enhance the food supply through novel applications, including nutrient and bioactive absorption and delivery systems; ingredient functionality; improved colors and flavors; microbial, allergen, and contaminant detection and control; and food packaging properties and performance. To determine the current state of knowledge regarding the safety of these potential uses of nanomaterials, an appraisal of the published literature on the safety of food-related nanomaterials was undertaken. A method of assessment of reliability of toxicology studies was developed to conduct this appraisal. The review of the toxicology literature on oral exposure to food-related nanomaterials found that the number of studies is limited. Exposure to nanomaterials in the human food chain may occur not only through intentional uses in food manufacturing, but also via uses in agricultural production and carry over from use in other industries. Although a number of analytical methods are useful in physicochemical characterization of manufactured nanomaterials, new methods may be needed to more fully detect and characterize nanomaterials incorporated into foods and in other media. There is a need for additional toxicology studies of sufficient quality and duration on different types of nanomaterials to further our understanding of the characteristics of nanomaterials that affect safety of oral exposure resulting from use in various food applications. © 2011 Institute of Food Technologists®

A number of obesity studies have been focused on identifying the relationships between socioeconomic status and physical activity involvement. In behavioral medicine, the limited data are available on obese people's physical activity and its related psychological predictors based on psychological theories. To identify the differences in physical activity and its related motivational attributes among normal weight, overweight, and obese adolescents and to find the effect of body mass index (BMI) and the Self-Determination Theory (SDT) constructs in predicting physical activity. One thousand seventy-one students ranging from seventh to ninth grades were randomly selected from three junior high schools in Seoul (359 normal weight students, 468 overweight students, and 244 obese students). A Korean version of Behavioral Regulation in Exercise Questionnaire-2 and Leisure Time Exercise Questionnaire were applied to measure the participants' motivational attributes and physical activity. Overweight and obese adolescents showed higher scores on amotivation and externally motivated regulations for physical activity than their normal weight counterparts. Internal regulation was more significant for physical activity in normal weight adolescent. However, there was no difference in physical activity among the three groups. Additionally, the findings identified that BMI and the SDT constructs were significant to explain physical activity. This study offers fundamental knowledge in gaining a clearer understanding of the types of motivation most likely to contribute to the initiation and promotion of physical activity in overweight and obese adolescents.

Physical therapists are at risk for work-related musculoskeletal disorders (WMSDs). Little is known of how therapists respond or of what actions they take to prevent injury. The purpose of this study was to investigate the prevalence and severity of WMSDs in physical therapists, contributing risk factors, and their responses to injury. As part of a larger study, a systematic sample of 1 in 4 therapists on a state register (n=824) was surveyed. An 8-page questionnaire was mailed to each subject. Questions investigated musculoskeletal symptoms, specialty areas, tasks and job-related risk factors, injury prevention strategies, and responses to injury. Lifetime prevalence of WMSDs was 91%, and 1 in 6 physical therapists moved within or left the profession as a result of WMSDs. Younger therapists reported a higher prevalence of WMSDs in most body areas. Use of mobilization and manipulation techniques was related to increased prevalence of thumb symptoms. Risk factors pertaining to workload were related to a higher prevalence of neck and upper-limb symptoms, and postural risk factors were related to a higher prevalence of spinal symptoms. Strategies used to reduce work-related injury in industry may also apply to physical therapists. Increased risk of thumb symptoms associated with mobilization techniques suggests that further research is needed to establish recommendations for practice. The issues for therapists who move within or leave the profession are unknown, and further research is needed to better understand their needs and experiences.

The purpose of this study was to determine the relationship among health-related quality of life (HRQOL), physical fitness, and physical activity in older patients after recent discharge from hospital. One hundred fifteen independent-living older adults (ages 70-92 years) were included. HRQOL (Medical Outcomes Study 36-item Short Form Health Survey), physical activity (Physical Activity Scale for the Elderly), and physical fitness (Senior Fitness Test) were measured 2-4 weeks after discharge. Higher levels of physical activity and physical fitness were correlated with higher self-reported HRQOL. Although cause and effect cannot be determined from this study, the results suggest that a particular focus on the value of physical activity and physical fitness while in hospital and when discharged from hospital may be important to encourage patients to actively preserve independence and HRQOL. It may be especially important to target those with lower levels of physical activity, poorer physical fitness, and multiple comorbidities.

The goals of this study were twofold: (1) to confirm a relationship between employee perceptions of psychological safety climate and safety behavior for a sample of workers in the rail industry and (2) to explore the relative strengths of relationships between specific facets of safety climate and safety behavior. Non-management rail maintenance workers employed by a large North American railroad completed a survey (n=421) regarding workplace safety perceptions and behaviors. Three facets of safety climate (management safety, coworker safety, and work-safety tension) were assessed as relating to individual workers' reported safety behavior. All three facets were significantly associated with safety behavior. Dominance analysis was used to assess the relative importance of each facet as related to the outcome, and work-safety tension evidenced the strongest relationship with safety behavior.

According to the European Federation of Organizations for Medical Physics (EFOMP) policy statement No. 13, "The rapid advance in the use of highly sophisticated equipment and procedures in the medical field increasingly depends on information and communication technology. In spite of the fact that the safety and quality of such technology is vigorously tested before it is placed on the market, it often turns out that the safety and quality is not sufficient when used under hospital working conditions. To improve safety and quality for patient and users, additional safeguards and related monitoring, as well as measures to enhance quality, are required. Furthermore a large number of accidents and incidents happen every year in hospitals and as a consequence a number of patients die or are injured. Medical Physicists are well positioned to contribute towards preventing these kinds of events". The newest developments related to this increasingly important medical speciality were presented during the 8th European Conference of Medical Physics 2014 which was held in Athens, 11-13 September 2014 and hosted by the Hellenic Association of Medical Physicists (HAMP) in collaboration with the EFOMP and are summarized in this issue.

Despite the reported harms and ethical concerns about physical restraint use in the critical care settings, nurses' intention to apply them is unequal across countries. According to the theory of planned behaviour, eliciting nurses' beliefs regarding the use of physical restraints would provide additional social information about nurses' intention to perform this practice. To explore the salient behavioural, normative and control beliefs underlying the intention of critical care nurses to use physical restraints from the theory of planned behaviour. A belief elicitation study was conducted. Participants and research context: Twenty-six critical care nurses were purposively sampled across gender, work-shift patterns and professional experience in five intensive care units of three hospitals in Spain. Data were obtained from a nine-item open-ended questionnaire and a focus group. Deductive content analysis was performed. Ethical considerations: Ethical approval was obtained from the hospital ethics committee. Participants were assured their participation was voluntary. Nurses framed the use of restraints as a way of prioritising patients' physical safety. They referred to contextual factors as the main reasons to justify their application. Nurses perceived that their decision is approved by other colleagues and the patients' relatives. Some nurses started advocating against their use, but felt powerless to change this unsafe practice within an unfavourable climate. Control beliefs were linked to patients' medical condition, availability of alternative solutions, analgo-sedation policies and work organisation. Safety arguments based on the surrounding work environment were discussed. Nurses' behavioural and control beliefs were related. Nurses should be trained in alternatives to physical restraint use. The impact of analgo-sedation protocols, relatives' involvement, leadership support and intensive care unit restraint policies on physical restraint practices need to

The present study evaluates eating habits and behaviors, and nutritional and food safety knowledge of a group of Italian adolescents. A dietary questionnaire previously constructed and tested was self-administered during school time. Each section was evaluated using a separate score. The study was carried out as a part of a nutritional surveillance project in the Aosta Valley Region, Northern Italy. Five hundred and thirty-two adolescent subjects, aged 15.4 +/- 0.7 years, attending the second year of secondary schools participated in the study. We evaluated eating habits, physical activity, meaning of healthy and unhealthy dietary habits and food, self-efficacy, barriers affecting healthy food choices, nutritional and food safety, weight, height, Body Mass Index (BMI). Only 37.0% of the sample have satisfactory eating habits; 18.5% have a very active lifestyle; only 8.6% have quite good nutritional knowledge, 2.4% have satisfactory food safety knowledge, although 43.7% have good hygiene practices. The results point out unhealthy behaviors influencing adolescents' eating habits and suggest which of these must be considered in order to develop tailored nutrition interventions, improving adolescents' consciousness aimed at adopting a healthy lifestyle.

Executive Summary Two studies were conducted to develop a psychometrically sound measure of supervisor health and safety support (SHSS). We identified three dimensions of supervisor support (physical health, psychological health, safety) and used Study 1 to develop items and establish content validity. Study 2 was used to establish the dimensionality of the new measure and provide criterion-related and discriminant validity evidence of the measure using supervisor and subordinate data. The measure had incremental validity in predicting employee performance and psychological strain outcomes above and beyond general work support variables. Implications of these findings and for workplace support theory and practice are discussed. PMID:24771991

These areas include academic research programs, use of computers in operational health physics, decontamination and decommissioning, dosimetry, emergency response, environmental health physics, industrial operations, medical health physics, new procedure development, non-ionizing radiation, radiation measurements, radioactive waste disposal, radon measurement and control, risk communication, shielding evaluation and specification, staffing levels for health physics programs, and unwanted or orphan sources. That is not to say that there are no operational papers dealing with specific areas of health physics, such as power reactor health physics, accelerator health physics, or governmental health physics. On the contrary, there have been a number of excellent operational papers from individuals in these specialty areas and they are included in the broader topics listed above. A listing and review of all the operational papers that have been published is beyond the scope of this discussion. However, a sampling of the excellent operational papers that have appeared in Health Physics and Operational Radiation Safety is presented to give the reader the flavor of the wide variety of concerns to the operational health physicist and the current areas of interest where procedures are being refined and solutions to problems are being developed.

These areas include academic research programs, use of computers in operational health physics, decontamination and decommissioning, dosimetry, emergency response, environmental health physics, industrial operations, medical health physics, new procedure development, non-ionizing radiation, radiation measurements, radioactive waste disposal, radon measurement and control, risk communication, shielding evaluation and specification, staffing levels for health physics programs, and unwanted or orphan sources. That is not to say that there are no operational papers dealing with specific areas of health physics, such as power reactor health physics, accelerator health physics, or governmental health physics. On the contrary, there have been a number of excellent operational papers from individuals in these specialty areas and they are included in the broader topics listed above. A listing and review of all the operational papers that have been published is beyond the scope of this discussion. However, a sampling of the excellent operational papers that have appeared in Health Physics and Operational Radiation Safety is presented to give the reader the flavor of the wide variety of concerns to the operational health physicist and the current areas of interest where procedures are being refined and solutions to problems are being developed.

Safety climate and attitude as evaluation measures of organizational safety.

PubMed

Isla Díaz, R; Díaz Cabrera, D

1997-09-01

The main aim of this research is to develop a set of evaluation measures for safety attitudes and safety climate. Specifically it is intended: (a) to test the instruments; (b) to identify the essential dimensions of the safety climate in the airport ground handling companies; (c) to assess the quality of the differences in the safety climate for each company and its relation to the accident rate; (d) to analyse the relationship between attitudes and safety climate; and (e) to evaluate the influences of situational and personal factors on both safety climate and attitude. The study sample consisted of 166 subjects from three airport companies. Specifically, this research was centered on ground handling departments. The factor analysis of the safety climate instrument resulted in six factors which explained 69.8% of the total variance. We found significant differences in safety attitudes and climate in relation to type of enterprise.

Leader-member exchange: Moderating the health and safety outcomes of job insecurity.

Probst, Tahira M; Jiang, Lixin; Graso, Maja

Job insecurity has been repeatedly linked with poor employee health and safety outcomes. Although research on high quality leader-member exchange (LMX) has demonstrated many beneficial effects, no research to date has examined the extent to which positive LMX might attenuate those adverse health and safety-related consequences of job insecurity. The current study extends research in this area by specifically examining the buffering impact of LMX on the relationship between job insecurity and safety knowledge, reported accidents, and physical health conditions. Furthermore, the study also examines whether positive LMX mitigates the typically seen negative impact of job insecurity on supervisor satisfaction. The hypotheses were tested using survey data collected from 212 employees of a mine located in southwestern United States. As predicted, job insecurity was related to lower levels of supervisor satisfaction, more health ailments, and more workplace accidents, and was marginally related to lower levels of safety knowledge. Results indicated that LMX significantly attenuated these observed relationships. The quality of the dyadic relationship between supervisor and subordinate has a significant impact on the extent to which job insecurity is associated with adverse health and safety outcomes. Practical implications for supervisor behavior and developing high quality LMX are discussed in light of today's pervasive job insecurity. Copyright © 2015 Elsevier Ltd and National Safety Council.

Physical activity declines across the adult life span despite the well-established links between physical activity and health-related, psychological, cognitive, and social benefits. We contrasted the beliefs young and older adults hold about how aging affects both physical abilities and physical activity and determined whether older adults' beliefs about physical aging relate to their engagement in physical activity. Using visual rating scales, 56 young and 49 community-dwelling older adults indicated the extent to which a typical woman or typical man aged 20-90 possesses six different physical abilities and engages in three different types of physical activity. Stereotypes of physical aging were ability- and activity-specific, and older adults endorsed more positive views than their younger peers. Stereotypical beliefs predicted older adults' engagement in moderate-intensity activity. This study offers intriguing avenues for future research and suggests that better understanding physical aging stereotypes may contribute toward designing interventions that promote lifelong physical activity.

The purpose of this article was to highlight important research needs related to physical activity in 3- to 5-year-old children. We identified research needs in 3 major categories: health effects, patterns of physical activity, and interventions and policies. The top research needs include identifying the health effects of physical activity, the effects of physical activity on the development of healthy weight, the effects of physical activity on learning and behavior, and the health implications of sedentary behavior. Research questions concerning patterns of physical activity include determining the prevalence of 3- to 5-year-olds meeting the current physical activity guidelines; the social and environmental factors that influence physical activity in home, preschool, and community settings; and how physical activity tracks into later childhood, adolescence, and adulthood. Research questions about interventions and policies include identifying the most effective strategies to promote physical activity in home, child care, and community settings and to reach diverse populations of young children, identifying effective intervention implementation and dissemination strategies, and determining the effectiveness of national, state, local, and institutional policies for increasing physical activity. In conclusion, research is needed to establish a full understanding of the health implications of physical activity in 3- to 5-year-old children, to better understand the nature of physical activity behavior in this group, and to learn how to promote physical activity in young children.

Experiences of physical and relational victimization in children with ADHD: The role of social problems and aggression.

McQuade, Julia D; Breslend, Nicole L; Groff, Destin

2018-04-16

The social risk factors for physical and relational peer victimization were examined within a mixed-gender sample of children with and without attention-deficit/hyperactivity disorder (ADHD). Participants were 124 children (ages 8-12 years; 48% boys), with 47% exhibiting sub-clinical or clinical elevations in ADHD symptoms. ADHD and oppositional defiant disorder (ODD) symptom counts were assessed based on parent- and teacher-reports; parents rated children's social problems and teachers rated children's use of physical and relational aggression and experiences of physical and relational victimization. A multiple mediator model was used to test whether there were indirect effects of ADHD or ODD symptoms on physical and relational victimization through social problems, physical aggression, or relational aggression. At the bivariate level, ADHD and ODD symptoms were both significantly associated with higher rates of physical and relational victimization. In the mediational model, there were significant indirect effects of ADHD symptoms on relational victimization via social problems, of ODD on relational victimization via relational aggression, and of ODD symptoms on physical victimization via physical aggression. Results suggest that there are distinct risk factors implicated in the physical and relational victimization of youth with ADHD and that the co-occurrence of ODD symptoms is important to assess. Clinical implications for addressing victimization in children with ADHD are discussed. © 2018 Wiley Periodicals, Inc.

Young adolescents who have little interest in participating in competitive team sports are at an increased risk for physical inactivity. Noncompetitive outdoor physical activity can provide young adolescents with increased opportunities to participate in physical activities that appeal to them and have positive health effects. The purpose of this study was to examine factors related to rural young adolescents' participation in noncompetitive outdoor physical activity to inform intervention design. Young adolescents aged 10 to 14 years old (N = 1,032) from 1 rural county completed a self-administered questionnaire assessing constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) related to noncompetitive outdoor physical activity. Structural equation modeling was used to examine an integrated conceptual model of hypothesized relationships among constructs. The hypothesized conceptual model provided a good fit to the data with greater perceptions of autonomy support and self-determined motivation having statistically significant positive indirect effects on participation in noncompetitive outdoor physical activity mediated by the constructs of the TPB. All direct paths in the model were statistically significant; however, the direct effect of attitudes on intention was weak (.08) and self-determined motivation had no indirect effect on intention through attitudes (.03). Constructs of SDT and TPB should be accounted for by interventions targeting noncompetitive outdoor physical activity among young adolescents. More research is needed to determine young adolescents' preferences for noncompetitive and competitive physical activity and the potential influence that noncompetitive outdoor physical activity may have on total daily physical activity.

Optimism about safety and group-serving interpretations of safety among pedestrians and cyclists in relation to road use in general and under low light conditions.

2012-01-01

Drivers are known to be optimistic about their risk of crash involvement, believing that they are less likely to be involved in a crash than other drivers. However, little comparative research has been conducted among other road users. In addition, optimism about crash risk is conceptualised as applying only to an individual's assessment of his or her personal risk of crash involvement. The possibility that the self-serving nature of optimism about safety might be generalised to the group-level as a cyclist or a pedestrian, i.e., becoming group-serving rather than self-serving, has been overlooked in relation to road safety. This study analysed a subset of data collected as part of a larger research project on the visibility of pedestrians, cyclists and road workers, focusing on a set of questionnaire items administered to 406 pedestrians, 838 cyclists and 622 drivers. The items related to safety in various scenarios involving drivers, pedestrians and cyclists, allowing predictions to be derived about group differences in agreement with items based on the assumption that the results would exhibit group-serving bias. Analysis of the responses indicated that specific hypotheses about group-serving interpretations of safety and responsibility were supported in 22 of the 26 comparisons. When the nine comparisons relevant to low lighting conditions were considered separately, seven were found to be supported. The findings of the research have implications for public education and for the likely acceptance of messages which are inconsistent with current assumptions and expectations of pedestrians and cyclists. They also suggest that research into group-serving interpretations of safety, even for temporary roles rather than enduring groups, could be fruitful. Further, there is an implication that gains in safety can be made by better educating road users about the limitations of their visibility and the ramifications of this for their own road safety, particularly in low

This study used a new Crime Prevention Through Environmental Design (CPTED) assessment tool to test the associations between physical attributes of schools and violence-related behaviors and perceptions of students. Data were collected from 4717 students from 50 middle schools. Student perceptions of risk and safety, and violence were assessed. Evaluators used the CPTED School Assessment (CSA) to quantify how well the physical elements of each school correspond to ideal CPTED principles. Generalized linear mixed models were used to adjust for school- and student-level characteristics. Higher CSA scores were generally associated with higher perceptions of safety and lower levels of violence perpetration and perceived risk in unadjusted models. Higher CSA scores were also associated with lower odds of missing school because of safety concerns in most adjusted models, with significant adjusted odds ratios (AORs) ranging from 0.32 to 0.63. CSA scores for parking and bus loading areas also remained associated with higher perceived safety (AORs = 1.28 and 1.32, respectively) and lower perceived risk (AORs = 0.73 and 0.66, respectively) in adjusted models. The CSA is useful for assessing school environments that are associated with violence-related behaviors and perceptions. The CSA might help guide school environmental modifications to reduce violence. © 2018, American School Health Association.

To determine consensus across acute care specialty areas on core physical assessment skills necessary for early recognition of changes in patient status in general wards. Current approaches to physical assessment are inconsistent and have not evolved to meet increased patient and system demands. New models of nursing assessment are needed in general wards that ensure a proactive and patient safety approach. A modified Delphi study. Focus group interviews with 150 acute care registered nurses at a large tertiary referral hospital generated a framework of core skills that were developed into a web-based survey. We then sought consensus with a panel of 35 senior acute care registered nurses following a classical Delphi approach over three rounds. Consensus was predefined as at least 80% agreement for each skill across specialty areas. Content analysis of focus group transcripts identified 40 discrete core physical assessment skills. In the Delphi rounds, 16 of these were consensus validated as core skills and were conceptually aligned with the primary survey: (Airway) Assess airway patency; (Breathing) Measure respiratory rate, Evaluate work of breathing, Measure oxygen saturation; (Circulation) Palpate pulse rate and rhythm, Measure blood pressure by auscultation, Assess urine output; (Disability) Assess level of consciousness, Evaluate speech, Assess for pain; (Exposure) Measure body temperature, Inspect skin integrity, Inspect and palpate skin for signs of pressure injury, Observe any wounds, dressings, drains and invasive lines, Observe ability to transfer and mobilise, Assess bowel movements. Among a large and diverse group of experienced acute care registered nurses consensus was achieved on a structured core physical assessment to detect early changes in patient status. Although further research is needed to refine the model, clinical application should promote systematic assessment and clinical reasoning at the bedside. © 2016 John Wiley & Sons Ltd.

Safety of dangerous goods transport is directly related to the operation safety of dangerous goods transport enterprise. Aiming at the problem of the high accident rate and large harm in dangerous goods logistics transportation, this paper took the group decision making problem based on integration and coordination thought into a multiagent multiobjective group decision making problem; a secondary decision model was established and applied to the safety assessment of dangerous goods transport enterprise. First of all, we used dynamic multivalue background and entropy theory building the first level multiobjective decision model. Secondly, experts were to empower according to the principle of clustering analysis, and combining with the relative entropy theory to establish a secondary rally optimization model based on relative entropy in group decision making, and discuss the solution of the model. Then, after investigation and analysis, we establish the dangerous goods transport enterprise safety evaluation index system. Finally, case analysis to five dangerous goods transport enterprises in the Inner Mongolia Autonomous Region validates the feasibility and effectiveness of this model for dangerous goods transport enterprise recognition, which provides vital decision making basis for recognizing the dangerous goods transport enterprises.

The Office of the National Coordinator for Health Information Technology is expected to oversee creation of a Health Information Technology (HIT) Safety Center. While its functions are still being defined, the center is envisioned as a public-private entity focusing on promotion of HIT related patient safety. We propose that the HIT Safety Center leverages its unique position to work with key administrative and policy stakeholders, healthcare organizations (HCOs), and HIT vendors to achieve four goals: (1) facilitate creation of a nationwide 'post-marketing' surveillance system to monitor HIT related safety events; (2) develop methods and governance structures to support investigation of major HIT related safety events; (3) create the infrastructure and methods needed to carry out random assessments of HIT related safety in complex HCOs; and (4) advocate for HIT safety with government and private entities. The convening ability of a federally supported HIT Safety Center could be critically important to our transformation to a safe and effective HIT enabled healthcare system. © The Author 2014.

This study examined associations between students' physical fitness and physical activity (PA), as well as what specific physical fitness components were more significant correlates to being physically active in different settings for boys and girls. A total of 265 fifth-grade students with an average age of 11 voluntarily participated in this study. The students' physical fitness was assessed using four FitnessGram tests, including Progressive Aerobic Cardiovascular Endurance Run (PACER), curl-up, push-up, and trunk lift tests. The students' daily PA was assessed in various settings using a daily PA log for 7 days. Data was analyzed with descriptive statistics, univariate analyses, and multiple R-squared liner regression methods. Performance on the four physical fitness tests was significantly associated with the PA minutes spent in physical education (PE) class and recess for the total sample and for girls, but not for boys. Performance on the four fitness tests was significantly linked to participation in sports/dances outside school and the total weekly PA minutes for the total sample, boys, and girls. Further, boys and girls who were the most physically fit spent significantly more time engaging in sports/dances and had greater total weekly PA than boys and girls who were not physically fit. In addition, the physically fit girls were more physically active in recess than girls who were not physically fit. Overall, students' performance on the four physical fitness tests was significantly associated with them being physically active during PE and in recess and engaging in sports/dances, as well as with their total weekly PA minutes, but not with their participation in non-organized physical play outside school.

Few studies have focused on the relationship between physical activity-related (PA) injury and overweight among youth. We analyzed data from the 2001 and 2003 Youth Risk Behavior Surveys (n = 28,815). Logistic regression was used to examine the independent effects of BMI and frequency of participation in vigorous activity, moderate activity, strengthening exercises, physical education (PE) classes, and team sports on the likelihood of PA injury. Approximately 14% of females and 19% of males reported seeing a doctor or nurse during the previous 30 d for an injury that happened while exercising or playing sports. PA injury was associated with participation in team sports, strengthening exercises, and (among females) vigorous physical activity. Controlling for type and frequency of physical activity, injury was not associated with being overweight (BMI >or= 95th percentile). Moderate physical activity and school PE classes may provide relatively low-risk alternatives for overweight youth who need to increase their physical activity.

To investigate relations of perceived worksite neighborhood environments to total physical activity and active transportation, over and above home neighborhood built environments. Observational epidemiologic study. Baltimore, Maryland-Washington, DC, and Seattle-King County, Washington metropolitan areas. One thousand eighty-five adults (mean age = 45.0 [10.2]; 46% women) recruited from 32 neighborhoods stratified by high/low neighborhood income and walkability. The Neighborhood Environment Walkability Survey assessed perceptions of worksite and home neighborhood environments. Accelerometers assessed total moderate-to-vigorous physical activity (MVPA). The International Physical Activity Questionnaire assessed total active transportation and active transportation to and around work. Mixed-effects regression tested relations of home and worksite neighborhood environments to each physical activity outcome, adjusted for demographics. Home and worksite mixed land use and street connectivity had the most consistent positive associations with physical activity outcomes. Worksite traffic and pedestrian safety were also associated with multiple physical activity outcomes. The worksite neighborhood explained additional variance in physical activity outcomes than explained by the home neighborhood. Worksite and home neighborhood environments interacted in explaining active transportation to work, with the greatest impacts occurring when both neighborhoods were activity supportive. Both worksite and home neighborhood environments were independently related to total MVPA and active transportation. Community design policies should target improving the physical activity supportiveness of worksite neighborhood environments and integrating commercial and residential development.

SafetyChem is a computer program that maintains a relational database for tracking chemicals and associated hazards at Johnson Space Center (JSC) by use of a Web-based graphical user interface. The SafetyChem database is accessible to authorized users via a JSC intranet. All new chemicals pass through a safety office, where information on hazards, required personal protective equipment (PPE), fire-protection warnings, and target organ effects (TOEs) is extracted from material safety data sheets (MSDSs) and recorded in the database. The database facilitates real-time management of inventory with attention to such issues as stability, shelf life, reduction of waste through transfer of unused chemicals to laboratories that need them, quantification of chemical wastes, and identification of chemicals for which disposal is required. Upon searching the database for a chemical, the user receives information on physical properties of the chemical, hazard warnings, required PPE, a link to the MSDS, and references to the applicable International Standards Organization (ISO) 9000 standard work instructions and the applicable job hazard analysis. Also, to reduce the labor hours needed to comply with reporting requirements of the Occupational Safety and Health Administration, the data can be directly exported into the JSC hazardous- materials database.

Hospitals within the United States consistently have injury rates that are over twice the national employee injury rate. Hospital safety studies typically investigate care providers rather than support service employees. Compounding the lack of evidence for this understudied population is the scant evidence that is available to examine the relationship of support service employees'perceptions of safety and work-related injuries. To examine this phenomenon, the purpose of this study was to investigate support service employees' perceptions of safety leadership and social support as well as the relationship of safety perception to levels of reported injuries. A nonexperimental survey was conducted with the data collected from hospital support service employees (n = 1,272) and examined. (1) relationships between safety leadership (supervisor and organization) and individual and unit safety perceptions; (2) the moderating effect of social support (supervisor and coworker) on individual and unit safety perceptions; and (3) the relationship of safety perception to reported injury rates. The survey items in this study were based on the items from the AHRQ Patient Safety Culture Survey and the U.S. National Health Care Surveys. Safety leadership (supervisor and organization) was found to be positively related to individual safety perceptions and unit safety grade as was supervisor and coworker support. Coworker support was found to positively moderate the following relationships: supervisor safety leadership and safety perceptions, supervisor safety leadership and unit safety grade, and senior management safety leadership and safety perceptions. Positive employee safety perceptions were found to have a significant relationship with lower reported injury rates. These findings suggest that safety leadership from supervisors and senior management as well as coworker support has positive implications for support service employees' perceptions of safety, which, in turn, are

Sci-Fri AM: Quality, Safety, and Professional Issues 07: Global Medical Physics Efforts: Closing the Gap

DOE Office of Scientific and Technical Information (OSTI.GOV)

Van Dyk, Jacob

Purpose: There is an increasing awareness of the disparity in Medical Physics needs between high income countries (HICs) and low-to-middle income countries (LMICs). This is especially evident with the growing incidence of cancer in LMICs. Projections from the recent Lancet Oncology Commission on Expanding Global Access to Radiotherapy indicate that an additional 22,000 Medical Physicists will be required by 2035 to provide uniform access to radiation therapy globally. This paper addresses possibilities and challenges associated with closing the Medical Physics gap between HICs and LMICs. Methods: Medical Physics and Oncology related organizations involved in providing support to enhance cancer therapymore » in LMICs were reviewed, especially as related to education, training and human resource development. Results: More than 35 organizations involved in addressing the cancer crisis in LMICs were found. Of these, 16 involve Medical Physics activities, with 7 being specific Medical Physics-related organizations. Ten of the 16 are involved in some LMIC activities with 6 having a major emphasis on LMIC contexts. Conclusions: The development of Medical Physics human resource capacity is a major challenge for LMICs. Fifty-five countries have no radiation therapy capabilities and by implication no capacity to train Medical Physicists. Overt attention with structured and altruistic actions by HIC contexts will help make inroads into the LMIC needs. Clear options throughout career structures in support of global health considerations combined with strong partnerships between interested parties in HICs and LMICs will enhance the development of safe and resource-appropriate strategies for advancing Medical Physics capabilities.« less

There is growing recognition that a sedentary lifestyle is being driven, at least in part, by environmental factors that affect individuals' physical activity choices and health behaviours. In other words, the environments in which we live, and with which we interact, have become ones that encourage lifestyle choices that decrease physical activity and encourage over-consumption of foods. However, evidence from community-led interventions to change local neighbourhood environments to support physical activity and healthy eating is lacking. This article summarises the research protocol developed to evaluate a community-led intervention "My Health Matters" aimed at reducing health inequalities relating to increasing physical activity and healthy eating as defined by community members themselves. This study includes three of the most deprived electoral wards in Stoke-on-Trent. In each of these areas, environmental factors including proximity of physical activity spaces, greenspace and leisure facilities, neighbourhood connectivity and walkability, land-use-mix and population density, traffic, safety and crime, and food outlets will be mapped using Geographical Information Systems (GIS). A community postal survey of randomly selected addresses assessing environmental characteristics relating to physical activity, perceived health status, social capital, fruit and vegetable consumption and levels of physical activity will be undertaken (baseline and at 2 year follow-up). Based on baseline findings an intervention will be designed and implemented over a 2 year period that includes the following; use of community participatory research to build effective community partnerships; use of partnership consensus to identify, prioritise and design intervention(s) related to specific health disparities; recruitment of local residents to help with the delivery and sustainability of target intervention(s); and the development of local systems for ongoing monitoring and evaluation

Moving forward with safety culture.

Radiation safety and protection of people are shared goals of the Health Physics Society (HPS) and the U.S. Nuclear Regulatory Commission (NRC). A positive safety culture contributes to achieving radiation safety and protection of people, which are important to both the HPS and the NRC. Through unprecedented collaboration and engagement with diverse stakeholders, the NRC and the stakeholders developed a Safety Culture Policy Statement. The policy statement defines safety culture and describes the traits of a positive safety culture. Consideration of both safety and security issues and the interface of safety and security are underlying principles that support the policy. Examination of significant events, both within the nuclear industry and in society at large, illustrates how weaknesses in these traits can contribute to the occurrence and consequences of safety incidents, including serious injury and loss of life. With the policy statement in place, the NRC is moving forward with outreach and education about safety culture. Health physicists and other radiation safety specialists play an essential role in enhancing safety culture.

Despite the detrimental effects of physical inactivity for older adults, especially aged residents of residential care settings may spend much time in inactive behavior. This may be partly due to their poorer physical condition; however, there may also be other, setting-related factors that influence the amount of inactivity. The aim of this review was to review setting-related factors (including the social and physical environment) that may contribute to the amount of older adults' physical inactivity in a wide range of residential care settings (e.g., nursing homes, assisted care facilities). Five databases were systematically searched for eligible studies, using the key words 'inactivity', 'care facilities', and 'older adults', including their synonyms and MeSH terms. Additional studies were selected from references used in articles included from the search. Based on specific eligibility criteria, a total of 12 studies were included. Quality of the included studies was assessed using the Mixed Methods Appraisal Tool (MMAT). Based on studies using different methodologies (e.g., interviews and observations), and of different quality (assessed quality range: 25-100%), we report several aspects related to the physical environment and caregivers. Factors of the physical environment that may be related to physical inactivity included, among others, the environment's compatibility with the abilities of a resident, the presence of equipment, the accessibility, security, comfort, and aesthetics of the environment/corridors, and possibly the presence of some specific areas. Caregiver-related factors included staffing levels, the available time, and the amount and type of care being provided. Inactivity levels in residential care settings may be reduced by improving several features of the physical environment and with the help of caregivers. Intervention studies could be performed in order to gain more insight into causal effects of improving setting-related factors on

For last five years Center for Theoretical Underground Physics and Related Areas (CETUP*) serves as a collaboration point for scientists from around the world interested in theoretical and experimental aspects of underground science. The mission of CETUP* is to promote an organized research in physics, astrophysics, geoscience, geomicrobiology and other fields related to the underground science and provide a stimulating environment for creative thinking and open communication between researches of varying ages and nationalities in dynamic atmosphere of intense scientific interactions. Scientists invited to participate in the program will not only provide theoretical support to the underground science, but theymore » will also examine core questions of the 21st century including: What is dark matter? How well do we know the neutrino parameters?, How have neutrinos shaped the evolution of the universe?, How were the heavy elements made?, What are the fundamental underlying symmetries of the Universe? Is there a Grand Unified Theory of the Universe? How do supernovae explode? Studies of Neutrino Physics and Dark Matter are of high interest to particle and nuclear physicists, astrophysicists and cosmologists. Ongoing and proposed Neutrino and Dark Matter experiments are expected to unveil the answers to fundamental questions about the Universe. This year summer program was focused exactly on these subjects bringing together experts in dark matter, neutrino physics, particle physics, nuclear physics and astrophysics and cosmology. CETUP*2015 consisted of 5 week long program (June 14 – July 18, 2015) covering various theoretical and experimental aspects in these research areas. The two week long session on Dark Matter physics (June 14 – June 26) was followed by two week long program on Neutrino physics (July 6 – July 18). The international conference entitled IXth International Conference on Interconnection Between Particle Physics and Cosmology (PPC) was hosted

To determine the sex-specific relationships between physical activity, aerobic fitness, adiposity (%Fat), mineral-free lean mass (MFLM), and balance and gait performance in older adults. Eighty-five female and 49 male sedentary, healthy, community-dwelling older adults (mean [SD] age, 69.6 [5.4] and 70.3 [4.7] years, respectively) were evaluated on habitual physical activity via questionnaire, aerobic fitness by a maximal oxygen consumption treadmill test, whole and regional body composition by dual-energy x-ray absorptiometry, and lower extremity physical function using gait tasks and computerized dynamic posturography. As expected, men had less body fat, more lean mass, and higher aerobic fitness than did women and tended to perform better on all lower extremity physical function tasks (all P Physical activity was not related to gait; however, fitness was related to gait in both sexes (r > 0.50, all P < 0.05). Body fat was related to gait in women (r = -0.38, P < 0.05) but not in men. Neither fitness nor body composition was related to balance in men, whereas in women, leg MFLM was positively associated (r = 0.27, P < 0.05). Women, but not men, with a greater ratio of body weight to leg MFLM performed worse on gait tasks (P < 0.001). There was an interaction with sex for %Fat on gait (P = 0.05) and for leg MFLM on balance (P < 0.05). In sedentary healthy older adults, the relation between body composition, aerobic fitness, and balance and gait differs between sexes such that women are more strongly affected by alterations in body composition. Lower %Fat and preservation of lower body lean mass have important implications for reducing the risk of physical disability, especially in older women.

Physical 'disability' in Bantu languages: understanding the relativity of classification and meaning.

The terminology related to 'physical disability' in proto-Bantu and in contemporary Bantu languages of Zone L are examined for a better understanding of African classification and meaning. The methods used in the examination include 'words and things' and ethnographic fieldwork. In proto-Bantu, nominal classes are used to categorize disability as both human and non-human. Based on the distribution of terminology, a support for differing regional and historical meaning is developed. The most ancient meaning links physical disability to 'becoming heavy' out of which variants developed. In contemporary Bantu languages in Zone L, the widespread use of the term -lema reemphasizes categorization in both human and non-human, and the use of meaning found in proto-Bantu is evident. However, ethnographic work in the same language area indicates that other terms are important to an understanding of classification and meaning related to physical disability in Zone L. These terms relate to sorcery or reincarnation as meanings attached to disability.
